I recently received a partial kit from an acquaintance and these are my attempts to fire it up for the first time. This is my first foray into tube amps, so please let me know if I am making any truly rookie mistakes.
I'm following the initial startup procedures as outlined by Bob, and the driver board tubes light up with no issues.
I placed the rectifier tube and two output tubes into the left side, and the rectifier tube arced and the 3A fuse blew.
I checked all of my connections for a short to ground, and tried again with a new rectifier tube. No rectifier arcing or blown fuse, but the quad cap smoked. At this point the power transformer seemed to have a markedly increased hum.
Shut down, replaced quad cap and re-did all connections for the sockets, rectifier tube, and quad cap.
Tried again, no arcing rectifier, no blown fuse, but the 120uf caps on the board smoked.
Picture is the amp in its current state, any recommendations would be welcome from here.
