OK, checked it with the table from here: http://www.radiodevices.info/esr/esr4_en.pdf

I left out all the caps that are OK:

C406 => REPLACE
C408 => DESOLDER it and check it again out of circuit. Same values ? Replace ! If good values, there's a short over the Capacitor somewhere else in the circuit !!
C410 => DOUBLE VALUES ?? I don't understand...
C411 => probably bad but...desolder and measure again.
C467 => REPLACE
C472 => REPLACE
C609 => REPLACE
C610 => REPLACE

SOUND BOARD:

C372 => REPLACE
C374 => REPLACE
C375 => REPLACE
C378 => OK but that C value (C357.1) indicates it's in parallel with a much bigger cap or something went wrong, desolder and check again

TR373 and 374 can't be tested with this device, these are transistors.

Jeez I had some problems focussing between all those numbers !!! Anesthetics are coming out....

Okay, that are a lot of bad caps!

About the C410, there are 2 pluses and minuses, we measured the one mentioned on the cap map, maybe this picture makes things clearer:



And of course thanks a lot for your work!

Yes, it's a big one. But on the bob roberts cab map they show were the minus is located, so we measured that one first. Hope you understand my gibberish!

If you look good, you see that only 2 holes have a lead in it  ;)

the left and right to be specific..
the top and bottom are just closed holes..
