Hey-Hey!!!,
Class A is soo much easier for a quick analysis. Draw the load line on the single tube curves, and then double it for the a-a primary load. This will usually give you a larger than expected number. The traditional a-a loads are from the 'Max Power' days for the most part.

If you want to look at an AB1 amp, all on a sudden things get more complex as the load changes from a-a/2 to a-a/4 when the other side cuts off. Not that that doesn't happen to a lesser extent in A...but, the first or second 'cut' analysis isn't going to need the details.
regards,
Douglas

....damn Thrintun!
