Hey, If I have one of these and want to change all of the tubes and if I buy tubes that are they exact same as the ones already in there, do I have to bias it or anything? Help me!

As far as I know you can just swap them if they are the exact same type. no bias needed

For the record, FYI, fact-of-the-matter, etc:

B-52 is a fixed bias amp.

Meaning that normally, you WOULD have to re-bias.
But it has no bias adjust. Bias settings are set so cold from the factory that practically any matched set will work without risk.

So pop your new tubes in and don't worry.

Further along the line, think about getting a bias mod, so you CAN adjust bias, if you so desire.
