It's beginning to sound like a partially shorted mod transformer.
I checked the resistances of the transformer earlier in the game and
they are nominal.

I have no idea but if mine is off by a factor of 4, would it work at all?
Could be bad 6L6's.
Or back to a reason for using 1614's perhaps?
Can you easily get high modulator plate current with audio applied?
Will the
mod plate meter peg or nearly so if you hit it hard?
Yes.
If it will that is an
indication that the tubes are good and the transformer may be shorted.
Except that the transformer appears to be ok.
To refresh.. we are talking about a max of about 75% modulation on
peaks but no problem over modulating at the base line.
