    I'm a hopeless romantic, I guess... Anyone care to get the specs on a TBS-composition resistor? turd/beer/smoke...

    I have seen the sparks fly out of white-cap tubes, though. And the 6L6GCs that lose the base pin and get 480VDC on the heater pin...

      Of course Leo is right. But indeed there have been many TBS comp resistors that have hampered amp performance without a pyrotechnics show. Once located and removed the amp returns to proper operation. I've seen it go both ways. The TBS comp resistor on the Fender shorting jack was even proposed by Enzo once regarding the survival of a Bassman that was used as a preamp for years with no load connected and had survived! The owner would plug the "EXT.SPEAKER" jack directly into another amps input and just turn the Bassman up a little bit If such a resistor forms and cooks/cures slowly, it's plausible.

        HA! I win! I win! Enzo said so!

        Actually I recently plugged the ext. spkr of my BM100 into the in on my DI box instead of the line out, then ran the Aux.Out on the DI to my regualr Bassman... Fun happened.
