About a month and a half ago I had a working Deluxe Reverb. At the time I was working on reducing hum and tweaking. Anyways one night I decide to redo the input jacks, re solder some grounds on the ground buss bar and shorten the choke's leads.
I turn the amp on and let it warm up, I go to my bench to wait....I turn around and there is smoke coming out the back. Filamnet winding (CT and all) completely charred black, insulation melted away. Now I thought it was my power tubes at the time for somereason, dont ask.
Fast forward to yesterday...Finally installed a new PT and brand new power tubes and fired it up with the amp out of the cab but hooked it up to a cab using a speaker cable. After no issues while warming up I flipped standby...Got sound, hit a few open strings just to make sure. Ok powered down, amp probably only on for about 3min total, 40sec of which was when the amp was fully on.
So today I put the amp in its cab as I wanted to see what the noise was like....I also wanted to check the bias. Anyways within 30sec of warming up I saw the faintest trace of smoke and immediately shut it off. When I took the amp out of the chassis I found the filament winding bubbled and all melty (clearly on the track of the last PT).
So basically power transformers aren't cheap for a 16 such as myself and I am getting super frustrated, super quick.... Such a piss off, I have built three amps prior to this one and they have been just great.
Any ideas?
Thanks...Chris
