What to do if Mesa Fillmore 50 Musical Instrument Amplifier power tube fails?

V
Valerie SandersJul 28, 2025
If you suspect a shorted power tube in your Mesa Musical Instrument Amplifier, quickly switch the amp to STANDBY and check the power tubes for one that's glowing red hot. If a major arcing short occurs between the plate and the cathode, IMMEDIATELY turn the amp to STANDBY, replace the tube and the fuse with the proper slo-blo type, and power up the amp using the power up procedure.
