[Amps] Pure signal vs AMPs idle curent

[Jim Thomson]

For those of you folks that have pre-distortion capabilities,  like the ANAN  xcvrs... and use an external tube linear amp.
Has anyone tried measuring the IMD results   with pure signal turned on....and also varying the bias and idle current of a 
tube amp,  like a GG triode ?? 

I would be interested to see the correlation  between TX imd and idle current, when PS is used.   Even if the IMD is slightly degraded,
down from an already high number to begin with....the trade off  may well be worth it.
