arts, that would be great, if you can find that article!
I think the manual says 24W intermittent, but since all but one of the original loads resistors was open (the 600 ohm was the good one naturally), I put in 20W non-inductive resistors on a couple terminal strips. So now the 4 ohm and 16 ohm can go to 40W, the 8 ohm to 20W. Of course, intermittent use with cool-down will allow quite a bit more. I may upgrade the power handling when I get around to getting more resistors. Right now all I have used it for is a 15 watt 6V6 push-pull guitar amplifier I am building for a buddy. It calibrated up nicely to the calculated IMD levels against my scope's FFT function, and I really like the built it VTVM for manually power output on a speaker or for checking small signal levels in the preamps.
(This is a toy I do not really need, but I always wanted one and I like using it.)
cheers
