Fender SPL 9000 , 1997 slave amp

About half the solder joints on the input sub-board are bad. A .25 and M&F
XLR each ch with no obvious reason why, as all sockets are individually
fixed to stout chassis metal . Even the never been used quarter inch sockets
have bad solder joints. The solder looks good otherwise.

Probably the sockets were soldered onto the pcb without laying on a jig. So
misaligned when fixed onto chassis. So inbuilt stress in board combined with
the board being in the internal hot air flow to the fan

unbalanced "reference planes". insulated 1/4 in i/p sockets . Lipped
insulator washer and star washer inside chassis but only the insulator
washer packing lines up with XLR rear faces, just that 1/10 inch or less
enough to stress the board/solder

Don't assume that the solder is good based on looks. If you saw Sitre
Magana at the Post Office for the first time, you would automatically
assume that he isn't about to start pounding his pud right in front of you.
