Fond memories, though probably 40 years old. The first amp I built of my own design used a 5kCT military surplus transformer in SE ultralinear with a 6BQ5. Got a back-loaded horn with 8" EV fullrange for free when a friend of my Dad converted to that newfangled "stereo" stuff. As I recall, it sounded really sweet.Without feedback, the output impedance will be a little higher than SET, though much lower than pentode/tetrode. Maybe a damping factor close to 1 rather than 2-3 like SETs (or 1000 for solid state!). With the right speakers, magic!
