Fillmore 100 head power drop

Post by willman » Tue May 25, 2021 3:02 pm

So, I've got a Fillmore 100 head I've had about 6 months but haven't been able to play much. Recently I've been playing more getting ready to gig, and I've been experiencing power drops in the Drive and Hi modes on both channels. Any ideas?

Hi.

Check the tubes: first preamp and then power amp... other easy check would be to patch the fx-loop with short cable.

Tubes may still be under warranty from Mesa
Current:
- Stiletto Deuce Stage 2
- Electra-Dyne 1x12 23” combo
- 4x12 Stiletto slanted

Gone:
- Mark III 60w/grx
- Diezel D-Moll
- Express 5:25
- Roadster head
- Triaxis / 2:50
- CAA OD-50
- Mark V
- 2x12 Recto Horiz.
- Bogner XTC
- Studio preamp

I had the same issue with mine. I replaced the quartet of power tubes. That fixed it for me.

Thanks, Billy. I've replaced all of the tubes. No luck.

I would email Mesa and tell them what's wrong. They are pretty good with support.
