SOLD! So doesn't seem like I'll be making any / many more multi-month international business trips, so really can't justify keeping this wonderful piece of kit around, not being used. This is a legit SET, Class-A, OPT tube amp. It has customer output transformers (Ni Alloy), and an unusually good built in Sabre DAC implementation. For a transportable tube amp, it's really hard to beat this thing. Drives most everything (except for very power hungry planars) quite well. Excellent condition (no dings, etc.), with two driver tubes. $900 net to me for Friends and Contributors.
