And with any tube amp its almost impossible to put enough feedback in the circuit to really do what needs to be done. So the next best thing is no feedback at all IMO. But you wind up with higher output impedance.
However, Harry's gear didn't show anything above the 4th, but it was there nonetheless. Any modern test gear would show it.

With that sort of efficiency you'll want 30 watts at least. - Ralph 09:54:37 10/21/20 ( 31)

- Yes- higher orders at only 80dB down will be audible as brightness and harshness. - Ralph 15:00:37 10/28/20 ( 2)

IMHO, simple discussions of wattage do not account for impedance and phase angle. nt - viridian 15:53:19 10/14/20 ( 0)
