Hi Flies --

You are exactly correct. The complete load line of a SE output stage extends both ways from the quiescent B+ operating point, in which case, it would then represent a peak to peak voltage value.

I was just trying to keep my presentation simple, and therefore discussed only the half of the load line represented by a positive grid voltage swing, and then treated it as a peak value only.

Of course as you surmised, whether you treat 1/2 of the load line as a peak value and divide by 1.414, or use the full load line's peak to peak value and divide by 2.828, it gets you to the same place, and same power output. Thanks for asking!

Dave

Thanks for confirming my guess, Dave! Sly things, those output transformers!

Hi!

I'm looking for a formula for calculating the output power for OTL amplifiers.
Can anybody help?

What about output the current? (I know I2xR....)

They get the same result, just Ohm's Law. It does not matter whether it's pentode or triode...
