Replaced both the 20 mfd filter caps and powered amp up on the bench. Still no output signal to speaker with volume control at 100%. There is a faint pop at the speaker when I turn the power switch off.
Here is the schematic that I found that most closely matches what I have:

Moderator previously commented on another forum member with a failed screen resistor. Could someone please point out the screen resistor(s) on this schematic so I know what to check next?
Checked AC voltage into rectifier - 288V. Checked DC voltage out of rectifier - 380V. Do these values sound correct? Does anyone know of a published diagram with checking voltages at specific test points?
