I have my 1973 PTP 100w super lead dimed all the time into a hotplate and I left it sitting there for awhile got distracted on the phone and I started smelling something and I KNEW it was my amp so I turned it all off and I blew my fuse one power tube and the power transformer cracks and sizzles and smells like something I cant describe and if I leave the pre amp tubes in with no power tubes it doesnt blow a fuse but it does crackle and sizzle the power transformer that is, so I'm dead beat broke and I'm hoping this is all it is I talked to david bray about it a little and he figures I was smelling ozone and the PT is cooked I read you can screw up the sockets and diodes or something like that, I've looked at the circuit and nothing looks like burned or abnormal, I haven't bought new tubes I have old tubes that came with the amp that I know work but I guess tubes can be bad when they look fine I dunno this is my first tube amp, thanks if anyone reads
