Checked the resistors.
Funny, all the resistors of the type, where the upper red arrow is pointing, are mostly within 1K from the target, and one of the 70K is within 10%.

However, all the resistors of the type, where the bottom arrow is pointing, are 60% - 100% up in value and need to be reeplaced. I have all values needed, the required wattage is fairly low.


The speaker checks out fine; both the FC and the output xfmr's primary are good.

And, sure enough, the power switch is intermittent and shows from open to 200-300 Ohm. Needs to be cleaned.
