What the easiest ways to measure the output impedance of a push pull tube amplifier?ThanksHank

Henry, do you mean the true Thevenin O/P impedance of the unit as a"near voltage" source, i.e. very low indeed, less than, say, 0.5 ohm?Or do you mean what is the nominal speaker impedance that it is set upfor, e.g. 4, 8 or 16 ohms?Cheers,Roger

DaveI was wrong it's only 10 watts. I know of no reason, perhaps someone here will tell us. They made tens of thousands of these so it must have had a need...

I'll see you on the third half of the show

unkown output impedance measurement?

Usual reason would be to drive several small speakers or to do so over a long run - like 100v line. Where a matching transformer is situated with the speaker.
