BTW,
Used as an IPA:
Is it possible to clean up the N4LTA 6M MRF-492 brick by idling it at
several amps (instead of 100ma) - closer to class A1 and adding some
negative feedback via an emitter resistor? [Assuming extra air and
heatsinking keeps it within its ratings]
Here's the schematic:

Right now the emitter goes directly to ground and the bias is obtained
through the base using R1 and D2. An extra -10db of 3rd order improvement
would be all that's needed if it worked.
