Ecpert village has over 100,000 videos of pure utter shit.

[MetalTCG]

so can anyone actually tell me what a bias tube means please?

[jhellen77]

Hey guys. Let me tell you how to bias a tube amp. This amp has an EL34. bye.

[BlackRose13579]

@jhellen77 A single EL34?

[Notespompon]

This guy will rip a solo and then have you whacked for stealing his yeyo

[HardRockLeadGuitar]

Does this guy think everyone here is an idiot or what ???

[bmwm3cs]

First off, you don't need to buy a matched quad for a "self-biased" amp. A 100 watt amp will most likely be push-pull, and two pairs of matched tubes will work just fine. Also, what was the point of this video? Expert village?

[theoryofgrey]

and this wuz pointless

[Baijidoom]

So basically, 10 out of 10 people clicked this video to learn how to bias their amps and your suggestion is to take it to a professional. Nicely done! 1/5 stars right there. These "expert" videos crack me up.

Hi im dennis downing- a TARD

[raffstd]

wow what is this ? amplification for tards by tards

[Erisblee23]

Boogie, Peavey, Soldano.... Self biasing?? UHHH, NO! No bias pot on a Boogie to trick you into paying too much for tubes from them, which supposedly are the right bias, but really aren't. How nice of them. And the first 12AX7 in a high gain amp is always the first to go(Squeal, hiss, pop), not the output tubes.

[peeziestp]

guy's a moron. "if it's a 50 watt amp, it'll have two power tubes."

then what about ac30s?

[HellBent1337]

Hah yeah, this guy sucks. I dont think he realizes that different amps have different styles of tubes.

[james335]

I didn't actually learn how to change amp tubes there!?

[slimyesli]

loll me neither

[kedsinger67]

That's bad advice in two ways. First of all the only true self bias is a cathode biased amp. second, preamp tubes last way longer than output tubes. If you listen to this video please send me all the pre-amp tubes you pull...LOL

[salemcripple]

Well, he probably recommends replacing them at the same time simply because it's "pulled apart" and might as well. As an auto tech, allot of times we replace Parts not because they are faulty yet, but because it's better (easier and cheaper) to replace it now than to have to pull it all back apart later.
