Gary Dodd makes some clean, mono blocks that run in ultra linear 4 EL34's per amp. 3 signal/phase splitter tubes, and the whole outfit can be retubed for under $300... with great tubes! If you find one with the cap upgrades he offers, you're in business.
I have the MK II 120s... with the cap upgrade. I surely can't complain what so ever about their versatility, and bang for the buck.
you want tubey sweetness? Roll two of the 3 signal tubes. More? Then all 3. Need fast, quick, dynamic, and full range output? Same thing again. With a mediocre outlay for some small tubes, these amps are several amps in one pair... and preowned, I've seen them go for about 2-2500, with the cap and a back up set of tubes! Less of upgrades course for the non upgradeed ones, which you can then get upgraded.
they hold bias well, and have on board meters so it's a cinch to do. I got mine config to allow for an outboard (more accurate) meters use with simple alligator clips which afix to the meter leads.
Great all around amps IMHO. Far gbetter overall than the BAT VK 60 for ex. and near the same price.
Good luck with whatever you choose.
