The closest to my OTLs from a xformer coupled amp I've ever heard...Goose bumps all over.
I've been running one of Gary's PP47's for a while now, and have been playing with similar designs using EL34 and 6V6/6AQ5 as time from work permits.
Got to agree, they can be extraordinary, better than almost all the bright emitter transmitter tube amps I've built (my reference standard up until recently). They make great electrostatic headphone amps too.
