In the Thread: How to get a LOT of SET power.

Post Subject: Starting point?Posted by N-set on: 5/7/2011

I fully agree with you on the holistic approach, I have been just trying to see if one can get at least one element of the package.
Or at least a +/- reasonable starting point for getting it. I reffered to your "school of thought"
on SE amps: 2 stage, no IT, no cathode followers, no multiple drivers, etc etc.
The excercise is to see if those constraints have any reasonable solution (without burning 1kW at 3kV power
to get 160W, which is doable with 2xGU48).
I have no idea how to interpret the results myself, hence I dared to post them here in a hope that
somebody would try to interpret them. You've mentioned elsewhere checking your B2 out and seeing distortion.
How does it compare to the ugly 20Hz waveform I've posted?

Still, before all that FFT fortune telling practices,
one basic question has no answer : how sensitive we are to the ULF distortion?
Romy, others, from your experience, how does it look like?

I would completely disagree on the power: 185W from 2 stage into 1 Ohm IMHO is very good!!!
This is a 450W tube, not a 1kW monster!
But the price of distortion seems very high?
