I recently discovered by amp doesn't suck due to a power tube switch I just made. I'm running it at around 7 on the volume and I'm wondering if it's a good idea to stop playing and get them biased before pushing them so hard more. It sounds great anyway and they are two pairs of matched EH El34's, just wondering if I should lay off using them until they get adjusted.

( It's going to be hard to stop playing! :P )

As long as the tubes aren't visibly red plating you should be alright.
A proper bias is never a bad idea though, albeit not always necessary.
