And furthermore although RX is high, 8R is floating. Looks like
something's keeping Q4 on the control board from turning on Q2. The

Replaced Q2 twice and got .5v on 8R both times before concluding
something had to be shorting 8R to ground. Found a little filament of
untrimmed toroid wire making a bridge, trimmed it, now we're though the
alignment and receiving 40m signals just fine.
One thing though...I'm certain I heard somebody here on the list
recently who had louder signals with the preamp *off*. And I'm pretty
sure Don told him what the likely reason was.
I just can't find the thread....anybody remeber? Don?
