I knob placement triggered my OCD immediately! Listening to you talk about the voltage at the speaker terminals, I kept waiting for you to warn us not to hook up the speakers with the power on. Your phrasing was ambiguous. I had my 1040 serviced a few years ago. I bought it in 1976 when I was in college for $150. My father was furious! I'm not sending you to college to party! Party we did! Got busted after hours with 50 people and a keg of beer in a 3 man dorm room. Great tunes, 400 albums between the 3 of us with 4 duplicates. What fun!
That's the right voltage Joe ..............I have several, this is the oldest version of the amp. Quasi complementairy output stage .............uses the same transistors in the PP , one of the reasons this amps sing so well .. AND never worry ...there's no DC offset on the speakers ( Capacitor coupled output ) Kind regards
Love to see something that’s it’s 52 years old still looks so good. And with people like you Joe and some others that do this type of work to keep this beautiful piece of art working for a very, very long time.
It looks like you're looking into the faulty capacitors. In my opinion, those amplifiers from the 1970s really need a recap. Even if the capacitors seem to be functioning fine, they might be dried out and on the verge of failure. I understand that we should first identify the root cause of the problem, but recapping them will definitely help prolong the lifespan of the amps for another four decades.
This stuff is fascinating to me! Wish I understood it better, exactly where to place the probes to test this stuff. I'll keep watching and reading! I acquired a Pioneer SX-680 very very clean, negligible DC offset I've been able to test. I'll test the rest as I am able! Thanks again for showing us these great units and what you do with them.
G,day from Sydney Australia. What is the brown component on the board. Looks like the colour of an old wax cap? Also the little brown round one; could be a fuse or cap? Thank you buddy. 🌏🇦🇺
With the age of the electrolytic caps (excluding the big cans) why not replace them all to have a better chance of not having an issue a week later? Seems like an extra 5 to 10 dollars to give a little insurance is a good idea. Thanks for your channel..... I am learning a lot about a niche of electronics repair I have not had experience in.
Hey Kreker I hear you when you mention about changing all the caps, that would be time consuming and customers are not willing to dish out alot to work on something that is not broken, I know it's a tuff pill to swallow but I also get it in a point view on the customers...they want it working , I find the capacitor wizard will at least find the bad caps that are causing issues and to replace them, the caps that are testing good will most likely be good for a long time to come and that's what customers wants... Some system I can replace up to 10-20 bad capacitors and some only 1 or 2, I find the Marantz very rare will I find a bad cap, pioneers are more likely to have bad caps...more than usual especially the early 70's thank you for watching and I have a marantz 1090 on the bench now, we'll see what I find on this baby.. Cheers Joe'sBench506
Thanks for the great video. I have a problem with this amplifier, sometimes when listening to the amplifier there is a crackle in the right channel (like static electricity discharge) it does not depend on the volume level. When I turn off the amplifier there is also a strong crackle in the right channel. When I disconnect the "main in" and "pre out" jumpers I use only the power amp and it works fine. I realize that the problem is somewhere in the pre amp, but I can't figure out where. Can you please tell me what could be the problem, what I need to check?
Hey.... It sounds like a leaky transistor...c1313 and c1312 are really back for that. Check the black legged transistors...sometimes tapping the transistor with a wooded stick will gave you clues also It's so hard to troubleshoot these ...
Hola Josè... Hermoso el video y ese ampli me gusta mucho. Acà en Argentina, es un poco difìcil conseguirlo.. Que opinàs de èl para uso de hogar? Con que limpiaste la placa frontal que quedò tan bien? Muchas gracias ..
Hi Josè... The video is beautiful and I really like that amp. Here in Argentina, it's a bit difficult to get it. What do you think of it for home use? What did you clean the faceplate with that turned out so well? Thanks a lot..
thank you Argentina. this amp is quit popular and easy to work on/ repair, yes it would be very nice for a home system, beautiful Marantz always did have a great sound, you maybe interested in my next video, I am working on a Marantz 1090...t see you on my next video Merry Christmas Joe'sbench506
Hi, let me start by saying that I don't understand the electrical engineering bullshit... in my life I have only changed the capacitors of my Ar11s... I would like to replace the filter capacitors of my Marantz 1060. Why do you discharge the capacitors before working on the amplifier? Do I have to do this too if I replace them? Thank you
Hi Max the reason I discharge especiallly the filter capacitors is that they store electricity, some don't store charge or some discharge on their own in time but you don't want to create a short by touching those capacitors as it could damage your electronic devices or get a shock. One thing you can do is with a MT test if there is a charge on the capacitors before your begin working on them...

good job and a fine amp 🙂
your video is very explicit, I thank you especially since I have a Marantz 1060 in my collection. see you soon!
Glad I could help!
