For those thru-board valve bases it looks as though you would have to
replace with standoff types to retain structural integrity but with
electrical isolation , as well as all that hard wiring and intermediary
isolation/ mounting points.
Looks like too much of a work up in comparison to paying Mr Marshall for a
replacement board.
I'm just wondering if this particular board , only 1 google ref, that they
will not have a replacement





I think replacements are generic, i.e. many different models share the same
output PCB.
Its the number of channels and other such stuff that are the variants.


Problem with repair, is that you might repair your V1 symptoms, but 6 months
later it comes back with the massively more disappointing bias destruction
problem.
Or vice versa.

The whole PCB is possessed, it needs to be exorcised.


It would be interesting if you could establish the physics and chemistry
behind all this though!



Cheers,

Gareth.
