Hmmm.... I'll have to speak with the future Dr. Schwips about intermodular distortion lowering IQ's in children. If it's just another risk factor on top of faulty genes then I think I can live with it. That cacti would suddenly turn pale and the basement would overflow with middle aged men getting their jollies courtesy of my toys, is highly disturbing. For the love of g-d, steer clear of the pinball machine!
Could the circuit be modified to accept a higher powered Directly Heated Triode like a GM70 tube? If the topology doesn't work with the speakers I have, where does my amp building project go from here? Specifically what other circuits are worth exploring or experimenting with given what I have said in my last post?
As I mentioned I think the speaker sounds polite or distant, which may be what you're referring to by lacking enthusiasm. My simplistic understanding of speaker loads seems in line with what you've said. You can customize the secondary of the transformer to suit whatever load you need. However I think if the load varies a lot you'll see nonlinearity of the frequency response with single ended designs. Rerurn to Romy the Cat's Site
