Hi all,
The SB-220 I've been rebuilding has developed a problem.
I put brand new tubes in it, and when I fired it up, within ten
minutes the filament transformer began *smoking*.
I thought maybe some of the wiring or components were burned, but an
inspection didn't reveal any. I removed the side panel and put power
back on the amp, and sure enough, the smoke is coming from the
transformer itself.
I can't find a problem in the wiring. Of course, it doesn't do this
this with the tubes removed, it'll merrily sit there all day with no
tubes.
Ideas? What have I done wrong?
Thanks,
Jeff/KD4RBG
