Those RCA and speaker terminals look great, which RCA's do you need to replace? Last night l just finished installing binding posts on the M-50, not as nice as the terminals you chose but came out nice all the same.
I´ve had my eye on one of those. I have a dedicated duty for it. And Japanese 100V MX-2000.

We use them at work for vibrator bowls for mini vial capping machines and syringe unscramblers running 24-7 at a constant value. I have absolutely no reservations about using one for my intended App.Can a variac be used as a full time power supply (set at any voltage) or are they only designed for shorter term test purposes?

Good to know, thanks.
I was looking over the manual today and have come up with another question. Adjusting the ZDR pots it says to adjust to the lowest distortion. So I'm getting the feeling that I would need a distortion analyzer for that? (Which I don't see a way that I can afford?) Or can that be done with an oscilloscope? All of this is something that I've never done yet so I still have a lot to learn.
Cheers,

HP 334A here.
They are handy.

The RCA's are for the input jacks.
I will be very interested to hear how you go with the M-70 distortion adjustment.
I've got the Quantasylum QA400 and it does run on windows.
Mine is the older, low input power model so I have to use a differential probe to run it on loudspeaker amplifiers. I honestly haven't used it much at all so I can't really give any pluses or minuses.
I really need to scoop out some time to sit down and really figure out how it works. Seems like a pretty useful tool from reading some of the threads where people used it.
The one l can see is to the left of the cable tie?. I feel for you as l have just spent hours reflowing about half of the joints on my pair, that's the one annoying thing with these early 80's Yammies, those damn dry soldered joints everywhere. Did you also find some on the meter board LED's?
I haven't attacked the meter board yet. I'm saving that section for last. I also bought a couple of different LEDs for potential bulb replacements. That's one of the reasons that I bought the 30vdc bench power supply. I can use it to mock up a led+resistor and check the brightness before installing them.
