I’m only a novice when it comes to tube amps, but I can’t find anything on this one. I know it’s likely 10 or so years old. Sounds great. Just want some specs or info on if or what I should swap out. The two EH 300bs don’t light up bright, I’m guessing something might be wrong, but it sounds fine.

It's a good amp from what I have been told. I would recommend you not remove the transformer covers unless there is some specific reason to do so.

300B do not have bright filaments.

I would recommend you find a good local tech now to service the amplifier when the time comes.
