The filament (heater) pin contactors in the tube socket of my SB-230 burned
up. But the tube is fine with full output. Rather than replace the "29-pin"
socket when no new tube is available under $800, I chose to convert the amp
to use a different tube. Anyone needing a good 8873 for rejuvenating their
SB-230, or any other purpose for that matter, can have this one -- on the
house.
