Since SET amps tend to have very nonflat frequency

I've already dismissed that with the contempt it deserves. Once again,
Krueger, you aren't talking to people who have to hog out the tube to
the maximum power because they bought "normal speakers". You are
talking to people who routinely run a 40W Pdmax tube loaded with such a
high impedance that it puts out less than 4W into speakers that will
never, ever, demand a whole watt. Get it through your thick head that
not all devices have to be run at maximum power; that applies only to
the poor who have no choice but solid state.

Lovely !

I guess you don't realise that *power levels* have *NOTHING WHATEVER* to do with frequency response abberations caused by a SET's highish output impedance.

This confirms my suspicion that you are in fact completely technically illiterate. In fact you could hardly have posted anything much more idiotic.

Any decently aware kid hobbyist would understand the interaction betwen 2 impedances where one varies with frequency. Even that basic fact is beyond you.

Now go back and do some homework on 'voltage dividers'. More likely you'll ring up whoever that bloke is who ghost writes the limited tech stuff your site is so short of.

Power level affects frequency response my arse !
