Al, that amp has a lot crap in it! How long did it take for you to find the 3 fuses?
Not long, Jim. The service manual includes a block diagram, a schematic, and a parts list. Which made it pretty easy to determine what fuses are being used, and where they are located in the circuitry.
And a quick look at rear panel photos that are available on the web confirmed that the fuses are not physically located on the panel.
Best regards,
