What amp is it? Which tubes are you replacing?

It is a bugera V22 and I'm changing the pre-amp tubes, I guess. I'm replacing a bugera 12ax7 with an electro harmonix 12ax7. (haven't had a look inside the amp and I'm first waiting a week or so to let the voltage die completely).

EDIT: I don't know if the tubes inside the V22 are some kind of bugera tube mimmicing 12ax7 or actual EH 12ax7's

I would not get all EHX 12ax7's they are very meh sounding. I strongly suggest JJ ec83, (new)Mullard 12x7, Sovtek 12ax7lps over the EH12ax7.

And no with preamp tubes, no re-bias required Just pull them straight out and put the new ones straight in

And u dont have to even let the amp cool down to do it. Hell i swap tubes so much, i sometimes forget to turn it off lol. I like to swap preamp tube types for different response. Instead of 12ax7 try anything u got in place of it. I really like the 12ay7 for less gain. And 12at7 for more of stevie ray vaughan type soundz. The absolute best phase inverter i e came across was a 12az7. Blew my mind.

This is true but you'd want to use a glove or a rag to prevent burning your fingers. They get damn hot.
