[QuadList] Got my VR 1200's

[Guy Spiller]

Actually, I never even got to the audio boards.  I noticed it as I was 
going through and taking inventory on the specs of the caps in the 
signal system and especially the TBC modules, since that was the area 
that was most flaky after I got it playing tape.
John did specifically mention the audio boards as "smokers" though.....I 
can only assume the Variac saved the day there, as it at least played 
back audio without having to replace any parts.
As an aside, I have yet to find a bad cap in a TR-70 power 
supply...except one small one in the regulator module in one machine.  
It's a good thing as the ones in the supplies themselves are HUGE and 
I'm sure virtually unobtainium at this point. 
In a 70, the smoke never comes from the power supplies....they always 
win....the poor resistors and caps elsewhere in the machine...always lose!
