So no thoughts on generator use , followed by rectifier failure.

It seems the mains fuse I have here was not necessarily the original one.
Someone looked at the amp and replaced the fuse, probably with this
probably
previously mechanically broken one (knocked about in a toolbopx). The
original may not have failed but assumed to have fused and so just
rectifier
failure.
Could generator brownout or spikes or something weaken a valve rectifier

it is ok while warm but gives up the ghost on the next powerup from cold?



I would have said not, but who knows ?
