So, when I tested my Blackstar HT60 soloist rebuild I blew the HT fuse (630mA). It had been almost working for ten minutes- sound but quiet.
I pushed in the OD selector and loud pop, a little smoke from under pcb (no signs of scorching tho) and it blew the HT fuse.
So I started testing again and saw that the neutral on the power socket was live and vice versa. Can’t believe I did something so stupid. As I am building this as a head, everything is the other way up, so I must’ve forgotten to invert the power socket. I call this stupidity tax. Every once in a while I do something so stupid, that I have to pay stupidity tax. I am thinking the PT might have blown - but need some guidance of what to test first
My question is what damage am I likely to have done? Now with everything wired correctly (and using a lamp limiter) the pilot light is on, but that’s about it. There’s about 100vdc at the plates (should be 570)
all suggestions gratefully received.
cheers
