The tubes in my Avatar 18 watt amp have gotten pretty tired and I think it's time to replace them. Any suggestions? I'm only looking for current production suggestions at this point. I've had too many bad experiences with NOS tubes and this amp eats power tubes too fast to justify the cost anyhow. The amp comes with 3 12AX7s and 2 EL84s and an EZ81 rectifier. I'd like power tubes that break up early and compress but sound good when breaking up. I've had Sovteks that break up nice and early but they sound like blat when pushed too hard and lack dynamics so I'm looking for other suggestions. I've been out of the game on testing tubes for awhile so I thought I'd see what y'all think. Thanks!
