Referring to the Fisher SA100 schematic and parts list (the Sam's has an error), can anyone explain why C16 (channel A) and C17 (channel B)are not the same value?
According to the schematic and my SA100, the left and right channels are mirror images except for this one difference.
This is a link for the Fisher Statesman, which appears to have the same amplifier schematic (albeit drawn differently) than the Sams version:

The capacitors in question can be seen on the Amplifier Schematic-C16 (12pf) and C17(5pf).
The Sams version has many errors

Errors noted so far on the schematic:
R37 should be 47K ohm
R39 should be 2200 ohm
7189 plate voltage should be 380v (not 270v)
On the Sams schematic
Channel A C12 is correctly labeled 12pf
Channel B has an unlabeled capacitor in same position 5pf
I have been replacing the components one by one and have verified that the caps in question are different, Channel A 12pf, Channel B 5pf.
I'm just wondering why?
