As usual, you did a great job in explaining and showing every step you took in restoring that Marantz. I learn a lot from your videos since you take time to explain all steps you take. Keep up the great work. I appreciate your dedication.
Great troubleshooting adventure on this classic Marantz. It always makes for an exciting time when the magic smoke comes out :) The way the RH amp settings were way out vs LH, maybe Tommy Toggle was in there playing when he shouldn't have been somewhere along the historical trail (we'll never know), it's been 40+ years since new. Anyway, thank you for your time, your customer will be most happy when he puts this beast back in service!
A forty+ year old speaker relay should at least have the contacts cleaned. I can guarantee I would have found significant series contact resistance. The symptom will show as volume drops mainly at low volume settings, then if volume is raised the sound comes back, only to drop out again. One of the very most common problems on vintage gear.
I’ve been watching several of your videos since I found your channel a few days ago and I appreciate your conservative approach, find the issue an replace only what is bad. Nice work
Lucky find on that power switch. I started to see burned power switches on high power amps and receivers back in the 80s when I was doing a lot of bench service. I told my customers to buy a high quality Wiremold outlet strip, and use the power switch on it to power up all their components. The inrush current is too much for those little switch contacts. At the end of a listening session, it's very convenient to shut off one switch and be assured all the equipment is off.
Hi Jose..at the time of the fireworks...i didn't think it was funny hahaha. Hope your doing well and you didn't get evicted with that Adcom... Good to hear from you buddy.
So Glad I found your channel. I am learning so much just watching you work your professional skills. My dad was an expert just as you are. I wish I have learned more from him. I just bought a Marantz 2265 and i have been enjoying if for about a month. It blew a fuse last week and I plan to pop to cover tomorrow and see what I've got for my money! thanks.
@ 48:26 in the video you are testing the output and calculated 115.52 watts. I thought that this was rated as 125 wats per channel RMS, as a new unit. Are you getting the measurement of 115 because ; A. You only did a repair of found defective parts, not a full restoration? B. The unit is old and there there may still be some weak parts not showing up? Thanks for the great video on an awesome piece of equipment. I own an 1180DC that needs a restoration. Would you be interested? Where are you located? Thank you for your time!
I am seeing more and more failing power switches as these amps get older (especially switches that also control volume). When using almost all of my equipment I keep the units powered on all the time, and use a smart plug/power strip to flip them on and off. Works well for me and keeps millage off of functional power switches.
LOL, I'm still @8:30 minutes, just saw the zap\spark and in my house, you could hear me loudly proclaiming a "Holy Moly" moment. Looking forward to teh rest of the vid to see what happened. I did watch the whole video, I have no idea how the power switch could cause sparks at the back end of the unit. Didn't blow a fuse? (Don't answer, these are rhetorical).
hai un interessante blocco di lampadine , nel tuo banco di lavoro . L'uso delle lampadine ad incandescenza è da sempre conosciuto , ma metterlo in rack sembra una buona idea
this comment translate to - You have an interesting block of light bulbs, in your workbench. The use of incandescent bulbs has always been known, but putting it in racks seems like a good idea. thank you !
-that is a tough decision and it all depends who you talk too. I love Yamaha and not sure if I would, especially CA810. if I had a choice in picking one of them, no money involve, I think I would pick and go with the Marantz hands down but to spend money to get this marantz... not sure if I would. -it's a interesting question though... I have never listen to this particular Yamaha you mention but I did listen to the Marantz 1250 and the sounds is impeccable. it's a amazing receiver no doubt. sorry I can't be more help!
Sweet work on this! Wow it was a trickster but hey as you said it's well designed and easier to work on that some less well built stereos. Great job. Wondering why this capacitor tester is better than the fluke when you are measuring ohms with both ?
Hi G.Fortin I like the capacitor wizard cause I can actually test in circuit for high resistance. If it's high ESR then I know I have a issue with that cap in circuit. Fluke measures the value of the capacitor but needs to be out of circuit for precision. The cheap ESR meter with the LED screen(under 20$) I have also is very useful as it measures capacitors, resistors and transistors and it's very affordable. Hope this help and welcome to the electronic world. I love it!!
@@VintageAudioFever thank you.. I will try to notice the cheaper meter in your videos. I had bought the Peak atlas esr70 but they need to be removed to test. Would be handy to be able to check before removing for sure. Thanks for reply !
What I don't understand is, You said, right away, at the beginning, that your D.C. Offset was high but then you plugged your speakers in!! Why didn't you adjust it before you plugged your speakers in?
Hi Bill, to respond to your comment, why did I hook up my speakers with DCV? I did find the DC voltage was high on the left but not enough to worry about damaging my speakers for a short period of time. It was safe to set the voltage with my speakers hook up. of course I say high meaning about 50mv....but still not going to damage your speakers , it's best to keep your dc voltage to minimal as possible.
Distinguished repair and accurate tracking of faults. I have benefited greatly from following your work. Thank you.

Hi Joe, thank you for the video and loved your electronics workshop!
Good afternoon. I already miss the black gloves)). As always, great work and interesting story!

Hey!!! Thank you for this comment.
So true about getting power switch...harder and harder to find.
Bonjour MrJoseph Leblanc ....Un bonjour de France ! Il faudrait nous parler français de temps en temps !
Nice job Joe. I had my doubts when the evil spirits shot out of it in the beginning but you saved the patient.
Haha well said, Spirit shouting out!!! Thank you for watching 👀 🙂
Hi Joe. Loved the fireworks just like the 4th of July. But again you showed that a bit of love and care works every time.
Hi Jose..at the time of the fireworks...i didn't think it was funny hahaha.
Hope your doing well and you didn't get evicted with that Adcom...
Good to hear from you buddy.
Nope still here but they are not making too much noise now. And in the summer I’ll be crossing the border by Niagara Falls.
You'll be in Canada...but I'm on the east coast hahaha

Glad to help, let us know what you found with your marantz 2265
Yes sir, you're one of the best, straight out of jamaica...
noticed hidden transistors could be tested as there are access holes in the plating
Great job!! Works flawlessly. I have another one for you to check out soon
Bring it to me before nice weather hits...haha
Great job, always
Thanks again!

Thats a great amp..look's pretty damn good as well.
Nice job...
Hope you're covid goes away real soon.

audio very difficult,, voice low, random background loud..
