Thanks Joe,
I failed to see the attachment and those numbers will give a very close idea what could be there to drive the tubes in an audio mode.
When troubleshooting a circuit problem and using a 'scope; the reference will always have to be Peak to Peak audio volts on the grids. There is no way, without more inaccurate calculations, to determine what wattage is available, and how that translates to peak to peak volts.
The O'Scope is the best piece of test equipment one could have in their shack.
I thought there would be some response from radio engineers who may have had some experience with the actual TX.

As you know Fred, to deliver the voltage required it has to be able to support the grid current required for class B service. A scope and a sine wave generator will tell you very quickly if the waveform is as it should be. Simple job!
