Hi all, just to update, finished the unit tonight, delighted, thank you so much!

Is it worth changing the loudness switches? I have the parts, but the originals are working a charm.

I am back folks, it seems my marantz is lacking in power.
I did a quick comparison with an sx450 Pioneer and the pioneer seems to have way more power!
Really quite stumped and not sure how to proceed, amp is all biased up @15mv and dc balance is set to 35v.
Just seems i have to pump the amp to 12 o clock with loudness on to get it to drive.
Using a real sensitive pair of redline 60.2 speakers 93db
Where do i even start, only other thread i found that is close is

Issue was with preamp board but mine is correct

Silkscreen is wrong i believe - cohibajoe has his P900 correct from what i can tell

I have had two 1060's, one l rebuilt just the amp board and the other had a full restoration. This behaviour you describe is quite normal.

Thanks for that, any other 1060 owners out there who have the same experience?
It would be much appreciated if there could be a consensus that one has to hit 12 o clock on volume to really get the 1060 moving

No worries, yes would be interesting to see what other owners think.

Aux and tuner. Fed with phone and PC.
Phono is as yet not properly tested, just quickly to see if any noise etc, all good, cannot remember how far i had to crank it.
I am literally thinking of redoing all the transistors on the board again, i could try and hfe match, but only have a cheap chinese transistor tester which i use a my leg pointer (EBC)
I doubt its accuracy is all that great, hfe seems to change whenever i test the part multiple times

Have you tried a different source such as a BluRay, DVD, or CD player? Phone and PC don't always have a strong enough signal. Do you have the volume on the phone or PC all the way up?
One more question: Are both channels equally loud (or not loud?)/ balanced? If they're balanced I don't think its your transistor or lack of matching. I know its a lot of work to change them all out.

Yes both channels are pretty closely balanced, at least to my ears, maybe left channel slightly quieter, but definitely not by much.
I suppose i could pop a cd player in to the mix, remember though, i compared this to a pioneer sx450 and on all those sources the pioneer gets louder at a much lower set point on volume pot. That is why i started to kinda freak out that i was missing something.
I need to get me a dummy load and learn to use an oscilloscope - measurements are probably what is needed really.
It would be nice to poll a few owners out there and see where they put the volume on the dial when listening though, might help ballpark things

Hello, I have two 1060s,
one seemingly original very clean (doesn't sound good, muddy, highs aren't crisp) and the other 1060 has had some select caps and transistors replaced (it sounds great, but is dirty and not fully-restored, actually has some rust on the chassis and the transformer paint is peeling off etc. Some wires are very sketchy up with blobs of solder too. It's pretty filthy actually).
So I am getting geared-up to work on the partially-fixed dirty one. I have parts on the way. This will be my first such effort, although I've built a few tube amp kits and done some repairs. Since the wiring is so bad I'll take the boards out and really clean it, I figure. Having the original one as a model gives me a little more courage.
Anyway - I don't have either hooked up at the moment, but both of these 1060s require 10 or 11:00 on the volume for loud listening, maybe even 12:00. I noticed this difference too. My 2235B is equivalently loud at 9:00, maybe louder; I never go past 9:00 with it.
So there's another random sample! Seems to be a characteristic of 1060s IMO. Just the way the volume is attenuated maybe? It gives you more usable range and maybe it's part of the design.
I'm really looking forward to working on this in the coming weeks! I'll probably be posting with questions. Planning to go super slow with it.
Here are some pictures of the one I'm planning to work on. Some of the soldering is horrifying, but it sounds really, really good! I probably shouldn't have plugged it in in hindsight. I'm going to re-do the sketchy wiring. Some of the wire has tape on it too. The worst soldering is on the bridge rectifier and the unswitched outlet. I wonder why someone had to dig into those?
