One think I missed was measuring the resistors for drift. % resistors are drifted more than 20% of their nominal value. Going from the schematic at
http://www.nostalgiaair.org/PagesByM...9/M0015509.pdf R1 which is 4.7M is drifted to around 7M and R2 which is 33k is drifted to around 50k. R10, R9, and R19 are all 470k. R10 drifted to around 560k (within 20% tolerance but I changed it anyway), R9 was around 700k and well out of tolerance. R19 was around 650k and made up one of the filters connected to the tone switch. In my opinion, this resistor really never affected anything because it just made up one of the tone switch filters, but I figured I'd change it anyway. R8 is 390 ohm and measured 465 ohm, This is just within 20% tolerance, but I think I saw silver on it so it must be 10% tolerance, so it's somewhat drifted. I never changed it yet because I only have a 0.5W 390 ohm resistor, the RCA parts list says it's 1W. The rest of the resistors are within spec and the voltages I measured are pretty much spot on with the service manual.
Also, what can I do with C36? The ceramic is cracked and I think it needs to be replaced. Can I just find a modern replacement of the same capacitance and that should work fine?
Thanks.
