Just found a 2325 4.5 hours away a couple of days ago. Way too good of a deal to pass up so now I am the owner of an awesome 2325! Will be going through it soon for a refresher!!
I recently sold my 2325 that I bought brand new in the 70's. The only obvious thing that was wrong with it was the main speaker switch that wouldn't latch. It was very heavy!
With Marantz 22 series..it’s all about symmetry, my favorite (which I have) is the 2240B only five knobs across the front, the black screen is wider to cover the small buttons This one is not too cluttered..The 2270 starts to get too busy
Love watching you at work on the old timers. I'm 77 and remember trolling the neighborhood on trash curb day and picking up all the tossed radios and bringing them home to work on. That was back in the 1950s. My dad was a ham operator and I learned to read schematics and solder at the age of 10. Still remember the fun of the challenge in trouble shooting and bringing them back to life. That was back when people threw away the beautiful multichannel wood veneer cabinet radios. Keep up the good work.
One of my favorite bands, Steely Dan. Just curious, is this a hobby or a side/main source of income repairing these hi fi's stereos? I probably can guess you do not live near me in California!
I have a 2330, she’s the queen of the fleet (of 7 receivers and integrated amps). I believe the 2330 allows for adding a Dolby module externally. *Nope: it’s an FM Quad output, not Dolby. Dolby sucked in the 1970s, it suppressed too much of the music. Dolby may have improved over time and, I believe, had a longer life on cassette decks than receivers.
I love my 2325. Just recapped the whole thing (including the main bulk caps), did the LED upgrade, new Vellum, restringing, new NPNs and PNPs in the preamp and phono, and deoxit F5 on all the pots, D5 on all switches. It looks spectacular and performs flawlessly with >165Watts per channel. Such a great receiver! Thanks to your channel for multiple tips. Next upgrade is re-veneering a vintage wood case for this beast.
@@samuelnorton7012 in the case of the small signal TO-92 NPNs it was a direct replacement 2SC1344 -> KSC1845 for the phono preamp. That is one of the most sensitive circuits for noise, so it's a good replacement to do for noise reduction. These both have EBC sequences. Sometimes the replacements do have switched orders, and you need to get the datasheets to make sure the pinout is mapped correctly.
I Can't say enough about your channel.You did a great job on the 2325 I enjoyed the video immensely. It was great to see how you carefully dissect a great piece of equipment. Also the not so great ones you bring back from the grave. I learn something on every one of your videos and appreciate your to the point explanations. Keep doing the things you love! It was especially cool to see the video of this awesome Marantz 2325 it was in the right hands and the end result speaks for itself. I look forward to more videos love the content you put out there. Thank you for sharing your knowledge and expertise my friend. Well done once again!
In 1972 I purchased a Marantz 2270 with optional walnut cabinet, Kenwood #777 speakers and a Phillips turntable from the Frankfurt Audio Club in Frankfurt Germany. I was stationed north of there when I was in the Army. They had fantastic deals on about every high end audio equipment you could think of. It served me well many years till a lightning strike ended it's life. Unbeknownst to me I purchased a European version. That was 220v 50 cycles. The instructions said to cut off the plug and install a standard 110v plug. The electronics would make the change internally. It worked for a time. Then one night I threw an outdoor party and brought it out to provide music. Well, I pushed it a little too hard, and popped an internal fuse. I had it repaired under warranty. It took a few weeks for the part to arrive from overseas. I got it back, set it up again and it immediately popped the same fuse. The repairman couldn't figure out the problem. He asked for the schematic. There was a different fuse for the 220v model. He installed the 110 v fuse. It was corrected, and went on to serve many years till it was struck by lightning. R.I.P. 2270.
I had my 2325 serviced and 30 caps and the filter caps replaced. Wow what a difference! It's like brand new. Pushing close to 135 wpc. Plenty of power and huge bass! LEDS really set ot off. This one of the best receivers to purchase and restore. Worth every penny.

What's the osciloscope you are using? What brands/models do you recomend for doing this?
Bought a Marantz Esotec ST-8 Tuner with oscilloscope at a flea market back in 2005 for 40 bucks. Sold it on eBay for 1200 bucks. I should've kept it. They are super rare. Thing was in mint condition.
The best thing about Marantz receivers is that flywheel station selector. They feel good to use and have the practical purpose of making large tuning adjustments smooth and easy.
Dude. DUde. DUDE!!!! This totally fixed my no left channel on my 2325!!! Thank You! Weird. Had no left channel. But if I cranked it up far enough with the balance to the left, mind you no sound coming from there, would come Blasting on. Started turning the speaker switch off and cranking it to avoid the blast. It really only happened once. But yeah. Why that would fix it temporarily, when the problem was the Pre to Main jumpers. Just barely not making contact I guess. Anyway. Thanks so much. 🤙
Beast !!! still enjoying me 2270 paired with the Kef Q350 sounds great for pricepoint and Yeah Sparkos have some amazing electronic componetes and Op-amps thanks for the video ! I have a Sansui G8000 i need to recap the Preamp board , The direct switch has static yes i cleaned it but still static and the left speaker will cut in and out but when using G8000 in amp mode i have no problems .
If you have CompactCassettes recorded with Dolby B and only a new Tape Player this Receiver is maybe a solution to play the recordings in full qualitiy.
Been doing this over 40 years and never seen a bad BA312 in the wild. No one has shown that the Sparkos is even reliable or sounds better. THD at least measures the same in the only comparison I'm aware of.
Great work on this 2325, these are such a nice model. Have serviced/overhauled a couple myself. They take a bit of time go over, but so worth it in the end. And agree with the power amplifier modules having wiring loom sockets, so much easier to work on.
I have a 2325 which I recapped myself. I’m getting some static when shifting the balance slide and a broken plastic clip. Would like to get it looked over and biased. Looking for someone near NY/ NJ. Any recs?
Hi, my 2325 needs repaired and/or restored. I already bought an extensive restoration kit. Do you, (Mr ah-ha fix it) take on jobs like this or could you, or anyone, recommend a good tech for the job? Thanks. Great video
I have a 2330B got it in 1980 from my Grandfather had bulbs replaced once and a couple services over the years it needs some attention but they're no longer any good techs where i live to service it😢
I’m not a tech and the nearest one to to me is a couple hours drive. However I do love the older marantz sound. I came across a 2325 that has been sitting for over 10 years in a locker that was my brothers. It looks like it’s in perfect shape, this one has a wood case and a metal venting grill on top that slides out towards the back Doesn’t have a scratch on it, once plugged up it lit up, all lights seem to be working. I tried it with speakers, headphones, record player snd radio mode. I get no sound at all, no audible click from the on off switch either. Other than that it looks perfect. Any ideas where to begin ?
Absolutely breaks my heart that you won’t accept repair jobs. I don’t trust anyone local with my Marantz 2325 that my Dad gave me 15 years ago. I was stupid and tried to replace the lamp/light bulb holder box that was melted as they do and did so while it was on and something touched the ground and that’s where I stopped. I’ll never sell it and don’t want to take it to any local place all in pieces. What can I do?!?!?
Hi I have marantz 4300 it’s been recapped I don’t hear the relay click on like my pioneer sx 1010 did.could it be just very silent also when the unit is on with no music playing I could here a very faint hum or buzz is this normal. Thank you for your relply
I have a Marantz 2325 is it possible I could send it to you and you can fix it completely for me I would greatly appreciate it thank you so much I am subscribed to your channel and love what you do thank you so much
Let's talk more about installing Sparko's op amps in vintage equipment. That's amazing. Can you do this with other vintage receivers? What a huge upgrade that must be!
Hi I have same receiver , May stereo light blew out, it looks like the indicator lights you can replace without taking the faceplate off ? Is that so , Thank you for your videos, I know it woul have to be soldered in place . Thanks again .
Have a 2325, My stereo lamp blew out, I guess the face plate does not have to come off to change the indicator bulbs, where they can be done on top just asking would love to know ?
Great job (As usual) !!! And in spite of that terrible cold. The Sparkos modules are cool, and especially nice if one of those unobtainable BA-312-M 's went out. Do you think there is an audible improvement with the Sparkos, or is it mostly a matter of replacing a part that could fail? Thanks
Holy smokes. I can't believe I watched the whole thing. I enjoyed watching your process thoroughly. I have a restored 2325 that I have been enjoying for the past 10 years. Like this example, it is cosmetically perfect. I need to de-ox some of the pots again (naturally). I was listening with my 2325 going through my JBL Century L100 speakers. I use my setup daily for hours and hours at a time. I LOVE Marantz receivers. I have ever since I was a teenager in the 1970's. Thanks again for a very enjoyable and informative video to geek out on!
I have been using a Marantz 2325 and four Klipsch speakers for over 30 years. I’d like to have mine re-capped ect. It sounds great as a matter of fact it’s been on for 3 months. I use it all the time so I thought it would be better to idle in stead of turning it on and off several times aday. I blow it out every few years ect. Love it ! My big khorns can cook , set of Belle’s with them is live entertainment !!
Thanks for the great video! I’ve got a 2238B that I need to work on. Your video will help. Question about dim bulb setup. Are simply putting the bulb in series withe load (receiver)? Will an led bulb work or does it need incandescent? Thanks
It's a good looking reciever for sure. Does it sound as good as it looks? I remember Marantz from hi fi magazines back in the 70's. 125w?? I had 45w in my Quad 33+303 amplifier. Enough. Unless you like to throw parties and annoy your neighbors. 😊
Excellent Video!! - I should have replaced the preamps but I didn't. Did replace the xstrs in the phono preamps however. I bridge rectified and filtered the dial / mode lamp power supply and retrofit LEDs for all lamps. A smart thing to do! No more 8 VAC running around with low level audio - now 9 VDC only. Current draw is reduced by a factor of 8 or more. Had to cut traces to mode lamps and bridged with 220 ohm current limit resistors and used White LEDs (20 ma). Made a new dial LED dial light strip circuit board with 11 Parallel X 3 Series Blue LED's with no current limit resistor. Since the source voltage is 9 VDC, the current across each of the eleven times 3 - 3 volt series connected LED's is 20 ma.. The 2 meters each got 2 Parallel X 3 Series Blue LED's . Blue color of the replacement LED strip is beautiful and perfectly even. Be careful of all the solid wire-wrap wires - they break easily - Don't be afraid of soldering the wire-wrap posts!. Take lots of photos before digging in. Label wires with masking tape if necessary! UV curing Bondic adhesive is very useful for strain relief and insulation. It is interesting to note that there was only one bad value/ESR Electrolytic capacitor out of some 120 or more replaced in my unit - better safe than sorry though!!
The last remaining or one of them that treats analog respectfully…fr the 60 to 70’s models…I always lived that name then…that metallic coolness or coldness😂❤…i btw recalls my teacher in an electronic course fr vocational course…a real guru but couldn’t not save our color tv…or the fixing y materials are too much for salvaging it😢…ty❤🎉 btw that was in the 70’s too when Sony were in Japan lol
I had one and it was awesome. Obviously I did follow the recommended procedure and pressure washed it with pool water and simple green. Muting circuit was bad and also fixed the power switch. Found an OEM unit. I repaired it and sold it for $650.00. Paid $150 from the original owner. The Dolby system was for the older cassette players.
I have a 2250 similar in appearance to this and a 2326B silver face. So here's my deal. I have my system paired with Klipsch KG 2.5 speakers and when it works, it works great. However, one of the channels, using either receiver, will cut out on me. Nothing out of one speaker or the other. I'm primarily using an Auris Blueme HD DAC. Are these issues with the serviced Marantz receivers, the serviced Klipsch speakers, the bluetooth DAC, or from interference to the speaker wire since I cannot avoid routing the right speaker past the high voltage power strip and TV gear? I had similar issues playing LP's as well in the past.
I bought a used 2325 about 10 years ago from a private owner. It was in a wood cabinet over the metal cabinet so it ran really warm. It was very dirty to the point that there were many tiny insects that decided to make their home in it. A repair shop had put in the ugliest LEDs on panel that were actually purple. Only reason I bought it was that it had a PERFECT faceplate meaning no scratches or marks anywhere. A good friend of mine who was a former Marantz bench technician from back in the days of this receiver told me that the only thing he couldn't repair was a scratchy faceplate. I shipped it out to him and he transformed it into the most beautiful looking and operating receiver I ever saw in my life. NO LEDs whatsoever thank God and he made sure the correct lights went in and even changed out the vellum paper that sits behind the fuse lamps and meters. He even had a plastic faceplate cover for the 2325 that the factory used to protect the faceplate during shipping so I just keep it in place just in case. Thats how much I respect it. I'm basically a separates person and have bought and sold many such separates over the years but every once in a while I get the urge to put my 2325 back in the rack and use it for a week or so just to keep it exercised and it never disappoints me. I'm saving it for my old age when I only have a minimum amount of space. In the end someone will just have to pry it out of my cold dead hands before I give it up.
Excellent video! I have a Pioneer QX747 and QX947, Kenwood Eleven and a few others that I bought to either restore or do what you just done here. Helps me decide. Thank you! Oh, I had a 2130 that I loved and had to sell 10 years ago. Miss it!
Always loved Marantz and live right near their factory building in Chatsworth, CA. (not there any more). I don't know anything about electronics and repair but couldn't stop watching how thorough you are. You are an audio ninja savant ;)
Great job, young man. My 2325 needs done as I’m sure I am the only one that has been into it. I do have one lamp out, last year. Every few years I take my air compressor and blow the insides out . I have the walnut cover also. It still sounds Great but at 50 years old , like me when you are old things get worn out ! I use my Marantz daily as I’m disabled now and listen to music more now. I can remember my children saying please Daddy don’t turn your music on. Hahahahahaha 😂 but it’s funny that now they listen to a lot of what I played to them when they were young ! I’m just scared of shipping ect. I know I am going to have to get done but it is like one of my children. I don’t want anything to happen to it, but good things. After seeing you do all that I know what I must do. Thanks !
I actually hate working on Marantz products,you although being young are doing very well on this receiver. I love the sound you chose and Yesi have owned some incredible audio over the years.
Gerard Stroh*** AH-Fix-it*** I Like Old Vintage Stereo Gear and Reel to Reel tape Machines and Some Recievers**** I Have A old Kenwood KR-7600 Reciever and I only Paid $50 Dollars at A Goodwill store about 25 years Ago and It Still Works Good and It Has alot of Power Like 70 Watts and It is Heavy*** The Kenwood has A good EQ tone Control and A 3 Way Loudness Control that you Don't See on Other Recievers and it Sounds Good**** I Also Have 2 nice Vintage Turntables and I have A Pioneer PL-600 Quartz Lock Direct Drive Turntable and It's Super Heavy and it's All Metal**** And I Have A Vintage JVC QL-Y5F Direct Drive Turntable and I Got That at A Goodwill Store for $50 Dollars about 25 years ago*** I also have some classic Teac and Tascam and Ampex & Otari and Akai Reel to Reel Tape Decks and and A Pioneer 1020L Reel to Reel Tape Deck and all the Teacs & otari & ampex are use 10 inch Tape Reels and akai's decks use 7 inch reels and they are work*** All from Gerard Stroh
Iv got a Marantz 2250B receiver with a scratchy selector. It did cost about $650 in 1976 here in Norway (scandinavia) . Its stowed away in the basement. I also like to restore it with a repair kit. Wanna like to use it with my vintage JBL's I has lot of. Really great video to watch here. Thanks🥲

Hello, I would like to have your honest opinion about a Marantz 2240, at a price around 430 us $ in good shape and good cosmetics. Thank you.
Should have never sold the 2325 . The Marantz dealer was hooked on me buying a Harman Kardon ? Go : Trio Pim Jacobs

Where do you order the lamp kits from? Apologies I could not understand the company.
I love my 2325. Just recapped the whole thing (including the main bulk caps), did the LED upgrade, new Vellum, restringing, new NPNs and PNPs in the preamp and phono, and deoxit F5 on all the pots, D5 on all switches. It looks spectacular and performs flawlessly with >165Watts per channel. Such a great receiver! Thanks to your channel for multiple tips.

Did any particular replacement transistors differ from originals as far as ecb bce ?

and Yeah Sparkos have some amazing electronic componetes and Op-amps
thanks for the video !
I have a Sansui G8000 i need to recap the

Its got "dublin". I like all the different models including the remote for the 4415 or the Oscilloscope thing on the 4000.
I have a marantz 4300 how much better sounding is the 2325 vs the 4300 is the quad a bad quality receiver thanks
I have a 2330B got it in 1980 from my Grandfather had bulbs replaced once and a couple services over the years it needs some attention but they're no longer any good techs where i live to service it😢
Hifi engine is no longer taking new members. If you don't have a membership you are out of luck.
I’m not a tech and the nearest one to to me is a couple hours drive.
However I do love the older marantz sound.
I came across a 2325 that has been sitting for over 10 years in a locker that was my brothers.
It looks like it’s in perfect shape, this one has a wood case and a metal venting grill on top that slides out towards the back
Doesn’t have a scratch on it, once plugged up it lit up, all lights seem to be working.
I tried it with speakers, headphones, record player snd radio mode. I get no sound at all, no audible click from the on off switch either.
Other than that it looks perfect.
Any ideas where to begin ?

Just had mine finally completely restored. I forgot to see what it benchmarks at. Hopefully a lot more than the 125wpc. Lol
I have a Marantz 2325 is it possible I could send it to you and you can fix it completely for me I would greatly appreciate it thank you so much I am subscribed to your channel and love what you do thank you so much
Does it have balance on the the tone controls?
I just found one for sale for 2 k Euros (2.2 k Dollars). This seems like a lot of money for this receiver. Or its worth it?
Let's talk more about installing Sparko's op amps in vintage equipment. That's amazing. Can you do this with other vintage receivers? What a huge upgrade that must be!
Hi I have same receiver , May stereo light blew out, it looks like the indicator lights you can replace without taking the faceplate off ? Is that so , Thank you for your videos, I know it woul have to be soldered in place . Thanks again .
Well, I just got my first Marantz recently. It’s a 1515, so it’s not as Booji at the bigger wattage models, but my god does it sound great to my ears.
OH - and YES - The FM Stereo Light Still WORKS with DC!!!
Have a 2325, My stereo lamp blew out, I guess the face plate does not have to come off to change the indicator bulbs, where they can be done on top just asking would love to know ?
Great job (As usual) !!! And in spite of that terrible cold. The Sparkos modules are cool, and especially nice if one of those unobtainable BA-312-M 's went out. Do you think there is an audible improvement with the Sparkos, or is it mostly a matter of replacing a part that could fail? Thanks
A piece of string around the back of the small knobs makes it easier to pull them off w/o having to pry.
I like your channel so much better than xray. You provide more detail.
My 2325 is doing the same thing only one Chanel is getting sound. Hope I can find a good technician in Iowa.
Do you have a list of parts that you replaced that would help to know which ones are the critical ones that need to be replaced. Thanks 😊
The 4270 also had a face full of buttons, dials and faders.
Love your content. Im not a Marantz fan. Sansui always does it for me. It is a solid sounding amplifier. Deacon Blues....
Love marantz and sansui!
now I found out my 2325 is dead on left side. not sure where to start. any ideas. thanks
You’ve been wrong before ?
Shocking !
I most certainly enjoy your channel 😉
Marantz 2325 is Powerfull than Pioneer sx-1250 and sx-1980..
So, what is that Lube u r using never heard of that?
125 watts per channel Marantz? I gotta find one of these things!
Holy smokes. I can't believe I watched the whole thing. I enjoyed watching your process thoroughly. I have a restored 2325 that I have been enjoying for the past 10 years. Like this example, it is cosmetically perfect. I need to de-ox some of the pots again (naturally). I was listening with my 2325 going through my JBL Century L100 speakers.

I have the 2325 care to do some work?
I have been using a Marantz 2325 and four Klipsch speakers for over 30 years. I’d like to have mine re-capped ect. It sounds great as a matter of fact it’s been on for 3 months. I use it all the time so I thought it would be better to idle in stead of turning it on and off several times aday. I blow it out every few years ect. Love it ! My big khorns can cook , set of Belle’s with them is live entertainment !!
give it a kiss ! Tell it you love it !
Thanks for the great video! I’ve got a 2238B that I need to work on. Your video will help. Question about dim bulb setup. Are simply putting the bulb in series withe load (receiver)? Will an led bulb work or does it need incandescent? Thanks
th-cam.com/video/VXnUr3xUonk/w-d-xo.html needs to be incandescent
Dolby was very useful. Wow
Not far short of 2k nowadays
It's a good looking reciever for sure.
Does it sound as good as it looks?
I remember Marantz from hi fi magazines back in the 70's.
125w?? I had 45w in my Quad 33+303 amplifier. Enough.
Unless you like to throw parties and annoy your neighbors. 😊
Excellent Video!! - I should have replaced the preamps but I didn't. Did replace the xstrs in the phono preamps however. I bridge rectified and filtered the dial / mode lamp power supply and retrofit LEDs for all lamps. A smart thing to do! No more 8 VAC running around with low level audio - now 9 VDC only. Current draw is reduced by a factor of 8 or more. Had to cut traces to mode lamps and bridged with 220 ohm current limit resistors and used White LEDs (20 ma). Made a new dial LED dial light strip circuit board with 11 Parallel X 3 Series Blue LED's with no current limit resistor. Since the source voltage is 9 VDC, the current across each of the eleven times 3 - 3 volt series connected LED's is 20 ma.. The 2 meters each got 2 Parallel X 3 Series Blue LED's .
Blue color of the replacement LED strip is beautiful and perfectly even.
Be careful of all the solid wire-wrap wires - they break easily - Don't be afraid of soldering the wire-wrap posts!. Take lots of photos before digging in. Label wires with masking tape if necessary! UV curing Bondic adhesive is very useful for strain relief and insulation.
It is interesting to note that there was only one bad value/ESR Electrolytic capacitor out of some 120 or more replaced in my unit - better safe than sorry though!!
The last remaining or one of them that treats analog respectfully…fr the 60 to 70’s models…I always lived that name then…that metallic coolness or coldness😂❤…i btw recalls my teacher in an electronic course fr vocational course…a real guru but couldn’t not save our color tv…or the fixing y materials are too much for salvaging it😢…ty❤🎉 btw that was in the 70’s too when Sony were in Japan lol
How can i get you to do mine
I had one and it was awesome. Obviously I did follow the recommended procedure and pressure washed it with pool water and simple green. Muting circuit was bad and also fixed the power switch. Found an OEM unit. I repaired it and sold it for $650.00. Paid $150 from the original owner. The Dolby system was for the older cassette players.
I have a 2250 similar in appearance to this and a 2326B silver face. So here's my deal. I have my system paired with Klipsch KG 2.5 speakers and when it works, it works great. However, one of the channels, using either receiver, will cut out on me. Nothing out of one speaker or the other. I'm primarily using an Auris Blueme HD DAC. Are these issues with the serviced Marantz receivers, the serviced Klipsch speakers, the bluetooth DAC, or from interference to the speaker wire since I cannot avoid routing the right speaker past the high voltage power strip and TV gear? I had similar issues playing LP's as well in the past.
Are those Advent or Dynaco speakers in the background - or neither?
I thought I caught a glimpse of what looked like a KLH logo.
I bought a used 2325 about 10 years ago from a private owner. It was in a wood cabinet over the metal cabinet so it ran really warm. It was very dirty to the point that there were many tiny insects that decided to make their home in it. A repair shop had put in the ugliest LEDs on panel that were actually purple.
Only reason I bought it was that it had a PERFECT faceplate meaning no scratches or marks anywhere. A good friend of mine who was a former Marantz bench technician from back in the days of this receiver told me that the only thing he couldn't repair was a scratchy faceplate. I shipped it out to him and he transformed it into the most beautiful looking and operating receiver I ever saw in my life. NO LEDs whatsoever thank God and he made sure the correct lights went in and even changed out the vellum paper that sits behind the fuse lamps and meters. He even had a plastic faceplate cover for the 2325 that the factory used to protect the faceplate during shipping so I just keep it in place just in case. Thats how much I respect it.
I'm basically a separates person and have bought and sold many such separates over the years but every once in a while I get the urge to put my 2325 back in the rack and use it for a week or so just to keep it exercised and it never disappoints me. I'm saving it for my old age when I only have a minimum amount of space. In the end someone will just have to pry it out of my cold dead hands before I give it up.
Would he do another?
@@LEWI1032 I don't know but I could ask. Does it currently work and are you located in the continental United States?
@@cpiscopo1 it works great just want it to be fine through and updated to last my lifetime. Yes I live in the us (Floridian)
Hello. Do you repair for business? I have a Pioneer SX980 I’d be interested in getting cleaned, checked and adjusted as needed.
Excellent video! I have a Pioneer QX747 and QX947, Kenwood Eleven and a few others that I bought to either restore or do what you just done here. Helps me decide. Thank you! Oh, I had a 2130 that I loved and had to sell 10 years ago. Miss it!
Always loved Marantz and live right near their factory building in Chatsworth, CA. (not there any more). I don't know anything about electronics and repair but couldn't stop watching how thorough you are. You are an audio ninja savant ;)
Your good at work you do. Which I had that kind of knowledge. Beautiful stereo, thanks for bringing back to perfection.
Great video! I still have my Marantz MR 235 receiver I bought new in 1978. Are there rebuild kits for these? You've inspired me :)
Do you sell them.
When I was in the army and in Germany 1970s a lot of guys would buy this at a lesser cost and ship them home.
i wish you would do a video on how to restring the tuner on it. i have this receiver but the diagrams don't show much.
Here's one for a Marantz 2015. Similar setup but obviously different. Hope it may help you. th-cam.com/video/zlxGeRYEQoI/w-d-xo.html
Great job, young man. My 2325 needs done as I’m sure I am the only one that has been into it. I do have one lamp out, last year. Every few years I take my air compressor and blow the insides out . I have the walnut cover also. It still sounds Great but at 50 years old , like me when you are old things get worn out ! I use my Marantz daily as I’m disabled now and listen to music more now. I can remember my children saying please Daddy don’t turn your music on. Hahahahahaha 😂 but it’s funny that now they listen to a lot of what I played to them when they were young ! I’m just scared of shipping ect. I know I am going to have to get done but it is like one of my children. I don’t want anything to happen to it, but good things. After seeing you do all that I know what I must do. Thanks !
5/16” works where 8mm needed. Me thinks. Thanks for the super informational information. 🤙
You're welcome to do my 2252b. In working order, I would just like it gone through from a competent tech and a relamp.
Vulfpeck: the official test LP for any vintage system's funkiness!
I’ve got a 2275. Beautiful and produces warm sound.
I actually hate working on Marantz products,you although being young are doing very well on this receiver. I love the sound you chose and Yesi have owned some incredible audio over the years.

I Like Old Vintage Stereo Gear and Reel to Reel tape Machines and Some Recievers****
I Have A old Kenwood KR-7600 Reciever and I only Paid $50 Dollars at A Goodwill store about 25 years Ago and It Still Works Good and It Has alot of Power Like 70 Watts and It is Heavy***
The Kenwood has A good EQ tone Control and A 3 Way Loudness Control that you Don't See on Other Recievers and it Sounds Good****
I Also Have 2 nice Vintage Turntables and I have A Pioneer PL-600 Quartz Lock Direct Drive Turntable and It's Super Heavy and it's All Metal****
And I Have A Vintage JVC QL-Y5F Direct Drive Turntable and I Got That at A Goodwill Store for $50 Dollars about 25 years ago***
I also have some classic Teac and Tascam and Ampex & Otari and Akai Reel to Reel Tape Decks and and A Pioneer 1020L Reel to Reel Tape Deck and all the Teacs & otari & ampex are use 10 inch Tape Reels and akai's decks use 7 inch reels and they are work***

Nice job! Always a pleasure to watch your videos. Thanks for your many great tips on parts and procedures. A+
It's too bad Marantz never made one of these receivers with all these features without having to have 100+ watts of power.
Is it for sale
Can you do a complete restoration on my SX1280?
Thanks so much for all the lamp info. What was that company that you got the kit from?
Can you explain the "dim bulb" test?

Hi
is there a parts source for electric componets...as well as re pop. switches and pots?
Iv got a Marantz 2250B receiver with a scratchy selector. It did cost about $650 in 1976 here in Norway (scandinavia) . Its stowed away in the basement. I also like to restore it with a repair kit. Wanna like to use it with my vintage JBL's I has lot of. Really great video to watch here. Thanks🥲
Hi my friend, Are you in Australia or Usa ?
What town are you in if I wanted you to do a repair? Thx
