must this be done every single time you change tubes? even if u change to the same tubes?
-
@Sethsilva13 Tubes are usually "burned in" during the process where the factory or distributor determines which ones get "matched" together. If you are really worried about it, you can just test them periodically.

Would it be wise to use this bias master when putting in a completely new set of tubes? If so do the tubes still have to be "burned in" or is it a simple plug and play scenario? Any and all help would be appreciated, since I'm no guitar tech, but I don't have the money to be taking thing to a tech for something as common as tube failure.

@LiquorWreckedEmGood You've just basically agreed with me in a smart ass fashion hahahaha. Don't fuck around with the inside of an amp...I have heard of a capacitor yes, I work as an electrical engineer. Congratulations on making yourself look a complete dickhead haha.

oh, everything should be "switched off" huh?
HAVE YOU EVER HEARD OF A C-A-P-A-C-I-T-O-R?
ONE OF THEM FROM A HIGH-POWER AMP DISCHARGING INTO YOUR BODY CAN KILL YOU, SWITCHED OFF OR NOT.
anybody reading this listen to me. you are a FOOL to fuck around with the inside of a high-power amp.
you won't get a do-over. it will just be all over.

Whilst your actually changing the tubes everything should be switched off anyway. The only time you have power is for testing so you shouldn't really have your hands in there!

I was going to order the exact same tubes for my amp. i have 4, but only two are bad, i found some online at guitar center. can i just switch out 2 or do i HAVE to do all 4. also there are three different options for my model 1-3low 4-7medium 8-10high. it is hand written on my current tubes a 6 which means i have to order the medium. is it ok if they give me any number between 4 and 7 or does it have to be a 6.

Discharging Capacitorsby arximidisxeno6,219 views
I'm surprised at all the biasing videos on here. One thing is missing from most of these videos and it's a warning about the fatal voltages insides of the capacitors in tube amps. These capacitors hold voltages high enough to kill. This stuff should really be approached carefully and with a lot of research.

@joedell71
Voltages don't kill. Amperes do.
