Missing page 7 from owner's manual
I downloaded the owner's manual so I can make a hard copy but I've found that page 7 is missing. Anyone else notice this? Anyone have a copy of page 7? Table of contents describe it as: Technical Description/Function then subsets as: Selector Switch/Tape Mon Switch/Balance and volume controls.
I can figure out how to make things work but still would like the hard copy as well.
Thanks
Missing page 7 found!
I just inherited my brother's 1060, and amazingly he still had the manual in pristine condition. I scanned page 7 for you.
This one still works nicely, but the power switch is worn and won't stay depressed. I tried taking it apart and bent the little piece that's supposed to travel in the groove, but that only worked until I put the entire thing back together again. Arg! Anybody know where I can buy a replacement power switch?
Marantz 1060 amplifier
I have very fond memories of the 1060. I bought it in high school in the early 70's. I have bought a Sony receiver since, but can't find it in my heart to part with the solid, elegant, simple 1060. It had enough power for me in my downstairs bedroom with attached Bose speakers (they finally gave out in the 90's.)
The volume control has, for years, had dust or something on it making it make a big scratching sound every time. I don't know if I dare take the amp apart and see if I can clean the volume control.
I still use it, I still love it. It cost $199.00 when I bought it.
May my wonderful 1060 live on
In college in the early 70s, with summer savings in my pocket, I shopped and shopped to find the best amp for the best money. I wanted a good one to power up my new AR2ax speakers and AR turntable and decent cartridge. I listed around at the stereo stores and decided on the 1060. I never regretted doing it. It became the most popular amp in the dorm, the speakers too. That sound was sweet, downright rich with a good record. 30 watts was way more than plenty for a dorm room, and later plenty adequate in my home's living room. The 1060 showed how nice a carefully-made transistor amp can sound. and that nobody should shy away from a great low-power amp.
I bought everything from a discount mail-order hi-fi warehouse in Texas. I think $200 for the amp, $100-something for each speaker, like $70 for the turntable, and half that much for the cartridge.
It all was stolen in 1981. The 1060/1090 amps were no longer made and used units could not be found in my neck of the woods - ebay didn't start for almost another 15 years. I replaced it with a new monster Kenwood, but after a while the big power got boring and for classical it was too shrill on the top end. So I gave it to my nephew and got something else, whatever it was (too muddy), and so on. None of them was good enough for my close listening except for another vintage Marantz.
Now I want to DIY the 1060 and so need the schematics.

Same here friend, amazing engineering for its time and great value with pre-amp output and mid-range control to name a few.
Channel Power Loss
Thanks very much for the documentation I have downloaded.
Before I start fault finding I thought I'd ask for any comments or suggestions as to a possible cause for my near complete loss of output from my RHS main amplifier.
The LHS power amp performs perfectly.
I suspect a capacitor related problem as some power output is actually only heard for a few seconds after I turn the amplifier off with the MP player still connected (as it does for the LHS amplifier).
Use of the remote speaker output reveals the same problem.
Any suggestions much appreciated.

I've just had a similar problem with my 1060. The problem was in a switch, or control potentiometer, it fixed it's self while troubleshooting it. I find a lot of stereo problems here.
Try a different speaker or swithch them If you haven't, plug all cables in and out several times to kind of clean them, especially the jumpers from the preamp to amp on the back, try different wiring to speakers if you've not done so, work the switcher in and out many times. Sometimes a switch contact will cause your problem. I doubt if it is a capacitor but anything is possible.
Cleaning switches, controls--remove them If you can do so, they can be cleaned without it.
Put a wad of paper towels under the switch or control while installed to catch the cleaners. Squirt a little WD 40 into whatever you are cleaning, work it in/out, on/off; spray it again. If you have some air, blow it out then use some electrical contact cleaner or denatured alchol to remove the WD 40. Blow it out again and let it set until dry. CAUTION-a switch turned on or off can creat a small spark internally between the contacts; if there is any WD 40 in it, IT WILL CATCH ON FIRE.
If you don't find a problem here then it's troubleshooting time. Leave a post if this don't help and if you can do a little troubleshooting and need help here, I've got a cheap easy trick here. Good Luck Bob

If you still need this advice: this is probably due to aging of the capacitors and can be repaired easily and cheaply by an electronics expert.

C 715 and C 716
My PCB has two electrolytic capacitors with caracteristics C 715 and C 716, that are not included in the schematic. Someone knows their correct values and because it contained? Thanks and hope to watch the response. Regards Charles
"mistery" unvealed for caps on marantz1060
HI
1060 and 1030 models, have the same PCB ( number P700 )and there are some differences.
The two capacitors C715 and C716 are mounted only in the 1030 model, and NOT in the 1060.
Their value is 100 mf.
They shunt the emitter resistances of H703 and H704 that in the 1060 model are 33ohms and in the 1030 are 100ohms.
So: don't worry and let everything as is. It's all OK!

Thanks Dave, and sorry! another Questions
When you turn the balance towards the left channel is heard and no serious or small means, to return to the center is more or less normal in both channels. Without more careful your response and hope very happy for you. Charles Regards
balance in a 1060
I'm not sure having get the question. I read several times your question, and may be you mean no result when rotating the balance control full counterclockwise. If so, then the control doesn't run.
May be a faulty potentiometer, but not only.
My question is: in center position a stereo program can be normally heard?
Check for any dry soldering on the PCB under the pot.
Then check with an ohmmeter when rotating to full left and right , if central tip goes to ground or not. Check tracks.

Thanks for everythink
Thanks for everything Dave, I resolved to change the connectors I disconnected some wires baffle. Greetings
