[VHFcontesting] Bias Current for Gemini 70-1K Amp

[K3SK at buckwalter.co]

What should I see for device DC current on the Gemini 70-1K amplifier?    I
replaced the Ampleon ART1K6FH device due to failure.    With the new device
installed the DC supply to the RF deck draws 1 amp powered on at idle.  When
PTT is engaged the current rises to 2 amps.   In an earlier conversation
with Roger at the DX Shop implied 1 amp Idq was what I should see.  The 2
amp reading seems high to me, but with no technical documentation on this
amp, I have nothing to base it on.  There is an adjustment on the RF deck
that is most likely for setting Idq.   Should I set this back to 1 amp with
PTT and no RF drive?
