Changing Tubes (sum pro jr content)

[dwarfstars]

Ok guys, my apologies if you guys are thinking: Not another of these again.

Anyway, I am using a fender pro-junior amp right now. From what I understand it is a fixed bias.

My question is, when replacing tubes, what should I be looking out for (i assume must get one identical to the stock since bias-ing would be much trouble)

And if there are any pro jr users out there, pls share with me what tubes you guys are using right now.

Thanks in advance. :wink:

Even if you get identical to stock tubes, you still need to rebias the amp.

You need a matched pair of EL84, you can try getting JJ tubes.

Then bring it to a tech to get it rebiased.

Process should take max 20min if he knows what he's doing.
