Default Behringer GMX1200H guitar amp, 2011 (?)

Sounds like the main caps have blown/shorted


Yes, in my opinion too small caps squashed into a small place on a
heated part of the board, considering the amount of space available in
this valve amp size, full width head .
18mm diam, x35mm, 105 deg C, is suspiciously small for 3300uF,50V.
Fixed 2 proper size 80V 3300uF to the cooler metalwork and so far
running fine.
Wire replacements to the burnt traces, leaving unburnt and unlifted
parts of the traces as "fuses"
