Would a bad tube still read the proper bias?
Assuming the bias was set properly in the first place, of course.

Re: Would a bad tube still read the proper bias?
Are you taking readings off the cathodes of your output tubes or your actual bias voltage on Pin 5? Is this a 6L6/EL 34 amp?Originally posted by chcjuniorAmps: 66 Fender BF Pro Reverb Combo,1973 50 Watt Marshall Head,Marshall 4x12 A/V Cab,Vox ToneLab LE,Vox VTH Valvetronix 120 Head,Vox AD 2x12 Cab,Roland Cube 20X

Yeah, because the bias meter will tell you that it's doing it's job, but won't tell you if it's about to blow, or is weak sounding, or or microphonic. In those cases, you'll have to use your ears, and also do the pencil trick......turn the amp up, and lightly tap each tube.Originally posted by Boogie BillComment

Pin 8 is the cathode on your amp...Originally posted by chcjuniorAmps: 66 Fender BF Pro Reverb Combo,1973 50 Watt Marshall Head,Marshall 4x12 A/V Cab,Vox ToneLab LE,Vox VTH Valvetronix 120 Head,Vox AD 2x12 Cab,Roland Cube 20X

When it comes to tube amps, each question yields an answer. I'll be back after I go look up cathode.Originally posted by STRATDELUXER97
