R37 is the feedback resistor with a value of 82,000, correct color code, they both tested about 585 ohms. Is this because they are in parallel with part of the output transformer or is there a problem?
I know this is not a problem but one of the original cap. is listed in the manual as .1MFD at 250 volts but was 1.0 mfd at 250 volts on this amp and was shown to be 1 MFD on one piece of the paper work, did they change this to .1 in later units?
This is a very clean and original amp, what can I do to the output boards without lowering the value to a collector. Like remove the 16 volt coupling cap, or change out the other caps, or update the resistors. Or should I leave well enough alone? I probably will want to sell it in the near future as I intend to purchase a VTA 120 kit in Nov. so I don't want to lower the value.
Yes it is a SCA with 7199's not a ST.
