I highly recommend the Atma-sphere M-60 Mk2.2's (and so does T.A.S.)! Ralph's equipment is VERY stable, no output transformer (but you would want a speaker with around 8 ohm impedance or higher) and has the sweetness of tubes, with the bass punch of transistors. There are adjustments for bias, and DC off-set. On this amp, adjusting these settings is about as difficult as throwing the power switch on, and adjusting the volume knob on your pre-amp. Don't let these adjustments frighten you...they're real easy, only one for each set of tubes in the amp (some amps require 2 or more adjustments FOR EVERY TUBE!), and once set, they stay set for a long time!
Help: low Maintenance Tube Amp short list.
I am making a short list of tube amps for audition. I would like to spend around 2000, give or take a couple hundred bucks. I would like to stay in the 50 to 60wpc range. And, last, but now least, I am looking for very low maintenance. I have seen some pictures of some tube amps, like the BAT models, with so many tubes that I wouldn't know what to do with them if they failed or needed replacement. Don't even ask me about biasing because I don't even know exactly what that is. Right now I have my eyes on a Conrad Johnson MV60. What else is there out there?
