OK. I have not spoken to a JWN amp owner who is unhappy. Sonically speaking, his amps are quite amazing. The highs are lush, the mids are to die for, and there is ample bass. There is an added dimension-an almost holographic soundstage display, practically three-dimensional.
My amp uses 8 output tubes. I am currently using EH 6CA7 variety, although the amp will take EL-34's, KT-88's, etc. It weighs 85 lbs and has huge Baldwin amp transformers. It is auto-bias.
For a detailed explanation of the circuitry, check out this review by Dick Olsher:

It is basically a grounded cathode input stage with a floating paraphase phase splitter. For contemporary reference, the $18K Esoteric A-100 uses a similar modified circuit.
I paid $1,500.00 LOL. Oh and did I say it sounds great?
