What a Genius at your prime age, to be so sophisticated in electronics and be able to fully restore an old vintage Marants 2230. A comprehensive well done job. A channel for all to subscribe and watch for sure. Thank you for doing this video for us. Catch you soon again!
Im similar in age to this youtuber and have repaired many vintage stereos and that through out my 20s, made going to school for electronics a breeze and ended up working for a hifi company repairing amplifiers and then ended up in aerospace electronics. Its rare to find people my age really into audio electronics, most of the electrical engineers I know dont work on electronics outside of work especially audio.
I bought the hakko solder pump and it cut my time down to minutes to repopulate a board. The components literally fall out and it makes the holes factory clean. Just watch the temp setting or you'll be sad when you lif a trace. I mark my caps towards the front of the unit with a sharpie so I never install them backwards. Boards occasionally have errors in the silkscreen. Old guy taught me that trick. Some guys would leave the couplers in and just replace the filter.
That was quite a project. Not just the restoration work, but all the filming and time editing the video before posting. Filming while performing the work has to really slow down the process as well. I have done some replacement of caps, resistors, and transistors and some other minor repairs myself on vintage equipment, but never wanted to take on the frustration of filming the work as well! Thank you for putting in the time to do all that.
I appreciate the extra effort to clean up old glue and replacing parts that have not failed, but I think it is debatable whether doing all this extra work is warranted. Sometimes it is best to just fix it and move on. Even new components can fail early, and old components can last a hundred years. Every situation is different. Love this channel. And it is great to see young people being interested in this. 👏👏
great vid... I have done 2 and had to take a break too. Ready to work on another but not another real restore. That was a lot of work as you said ! Nice job !
Wow! When you restore a receiver, you RESTORE a receiver. I worked on electronics for 6 years in the Navy and repaired office machines for 40 years and did a lot of soldering but I wouldn't try this. I have a 2220b that sounds perfect and I might replace the power supply caps and filter caps but that's it. Thanks for a great video!
Great video and what a complicated project for sure! I am waiting for a snowy day to rebuild my Pioneer SX-780 (it works fine, but it is 44 years old). I have all the replacement caps and semiconductors for everything except the tuner board. I never listen to the radio so I didn't bother and I can always do it later if needed. I also purchased the reversed engineered STK50 replacement power packs. Will be a fun project for sure.
Ah the famous powered washed receiver. Funny how the haters tell you, that you can get electronics wet. Tektronix among others have done it for decades. Had a very clear and easy protocol to do it. I done a couple like that, and nothing happens if you dry it perfectly. Alsi they hate ultra sonic cleaners. Gret video and work. ❤
Great job. I have restored several vintage / older Audio Amplifiers. As you say it's good fun but because of the concentration levels required it can also be stressful by the time its finished. But I still go back and do more. Good luck. We don't do thanks giving in UK but have a good one.
Regarding the PSU and POWER boards, run/repair the amp at full output power at 4ohms load, look with IR at the boards and you will know which components to check and focus on.
A Wednesday surprise from Aidan...Happy Thanksgiving! Nice job on the re-cap, lots of work involved and your right about the burn out thing, if it becomes a job it's no longer any fun. I make for sure I'm not under any time constraints when doing any hobby work but I'm not a YT content maker so YMMV. Next episode should be interesting as well. Nice video, very enjoyable, thanks.
That glue can be corrosive and conductive over time. Its a great idea to remove that stuff as you did. If it's on any resistors or other components, I would replace them too. Keep up the great work. For example, I would replace R801 on that power supply board you first worked on as it appeared to have some of that glue on it as well.
for the past 20+yrs i replace all carbon resistors to 1% film type and all ceramic caps with film. time consuming but you will not believe how tight and precise the sound is. it also makes your system more efficient making it unnecessary to turn up the sound.
Hi, first of all I want to thank you for your efforts of the knowledgeable videos that you shared with us. Very impressive 👏 My question is did the acetone doesn't remove the marked labels on the boards?
Thank you for the video great work. I just got one like this but no sound coming out on both channels any suggestions on how to target it, also do you have the replacement parts list for it.
FYI. if you use soldering flux on the connections, the solder will flow out and not be so globby. It also creates a much better connection with less chance of a cold crack.
Thanks for your videos, I love watching them. I restored my 2230, but the source indicator lamps ( phono, tape, aux, etc.) keep turning on and off by themselves whenever they want. Most of the time when the receiver is cold they are on, and after 30 min they go off. Any idea why? Thanks
Sounds like a loose connection. Trace the power wires back and see if they're all connected properly. If you converted to LED make sure the lamps have a resistor in series with the LED.
Great job, thanks for showing this 2230! Do you have the Digikey BOM that you could possibly share for this please? The shots were blurry at times when you tried showing some of the part numbers. I have a 2230 too, which has been partially recapped, but it will need totally gone through at some point, with the semiconductors and whatnot most likely replaced, or I'm at least hoping have backup parts for it on hand anyway, should something fail. Anyway, hope you have a great Thanksgiving! See ya on the next one. 🍻
Great video. Can someone help me with a very basic question about the Marantz 2230. I just bought one and am trying to connect my turntable to it, but I do not see a grounding screw that would fit my double forked (dont know proper name) grounding connector. Anyone?? 🙏
Check out this little YIHUA 929D-V Desoldering Iron, it’s cheap. works amazing, think I paid $25 for it. I do have the $250 Hakko but just got this little one and I’m super surprised works well.
I like what you are doing! I also subscribed and follow your channel! I know it might sound picky, but please remove your ring. I would hate to hear that you were hurt because of it.
Hello from Meaford Ontario Canada :When installing capacitors consider putting anti acoustic caulking under each capacitor to help reduce vibration, doing this will increase the sonic signature , I did this to my Nakamichi CDP 2A Cd player and the sound is now magnificent what a difference anti acoustic caulking can make for dampening
You see those zener diodes fail very often ? Gunshot replacement of components again. Bad practice I think. For a zener you could feel their temperature after 20 minutes, and if you >really burn< yourself you could replace them, they had a hard life, otherwise better leave them as they are. Again, why replace a working zener in the first place, but when you do better keep them as they are rated. And following that, > NEVER < replace a 7 V zener with a 7.5 V ! The voltage of a zener is a given thing, it is what it will GIVE the circuit, and not what it can take like with a cap, huge difference. Now the whole circuit that needs that 7V is going the rest of its life on 7.5V. Nice if it causes an error in future, nice error to find for the next guy. Also keep eye on the manufacturers power ratings, that also effects the working voltage in the circuit. For the plastic transistors, while you don't address a metal case transistor, "I don't like those" is not enough for me. The transistor with low gain has a very simple function, and is probably rescued from the bin by the manufacturer to do this simple job. Sorry for my rand, there's enough positives to read in the rest of the comments.
When installing capacitors you will want to keep with the voltage rating ...why?...because if you use higher value voltage ratings you increase distortion through ESR
Real techs don't make videos,or pressure wash electronics at the car wash.I feel blessed for guys like this that make videos,however.Keeps others from being any threat of competition.Not that I have to worry about that,anyways.
@@M-P-X Many resistors are carbon composite, so it would be almost impossible to replace them all. As long as they measure OK, why replacing ? He is often busy with gunshot replacement of parts, like transistors, like diodes, and now even the zener diodes, so "why not the metal casing too, it could corrode....". So my remark was purely cynical.
@@erikdenhouter Why nit pick the guy? This is a field where 1 - Theres not many people interested in doing the work anymore ( techs are getting older ) 2 - Theres life long techs that do sloppy work ( while maybe shotgun at times his work is clean and not sloppy at all ).. Give the guy some credit for helping others and explaining things very well.

He just replaced a good zener diode of 7V with a 7.5V. Bad practice. I hope he takes the time to read comments, I cannot scream any louder.

merci beaucoup, je vais revenir vers vous
Awesome video. How much does it usually cost for a restoration? Thank you.
Ok.... Last comment... Did you replace all the non board mounted electrolytics as well? BTW.... Love watching you work and learn as you go!
Thank you for the video great work. I just got one like this but no sound coming out on both channels any suggestions on how to target it, also do you have the replacement parts list for it.
Hi, did you keep the receiver on when you were checking the ohm on the resistors?.
Great vid. I wonder if you can comment on your shop table lamp? How is it performing.. shadows..glare.. etc. I've been looking and some hurt my eyes.
FYI. if you use soldering flux on the connections, the solder will flow out and not be so globby. It also creates a much better connection with less chance of a cold crack.
Not necessary unless using surface mounted components. You must be into computers.
Thanks for your videos, I love watching them. I restored my 2230, but the source indicator lamps ( phono, tape, aux, etc.) keep turning on and off by themselves whenever they want. Most of the time when the receiver is cold they are on, and after 30 min they go off. Any idea why? Thanks

Have one of these new old stock........
I just recapped my 2230. Not fun. Especially the board below the board.
Did he stop making videos?

which vibration 🙃

As to those transistors you decided not to replace. Why not at least test them ands see if they're still in spec at least as far as gain is concerned?
You see those zener diodes fail very often ? Gunshot replacement of components again. Bad practice I think.

Going to 100V caps is a bit over the top indeed.
Good point,
Sometimes it depends on what is available or in stock.😊
Power washed!
Yeah,you're learning.There's just something about your face.Anyways,good luck with your hack rebuilding.Youll make a good boss one day.

All the resistors are carbon resistors, shame on you 😮
And the casing is metal, so why not replace it for stainless....

What is the purpose of the coil on the filter caps? noise?
