[Hammarlund] HQ-180 versus HQ-180A

[Grant Youngman]

Nothing of consequence other than solid state rectifiers and the 1st
conversion oscillator tube is powered on when the radio is off in the "A".
Overall, either is a fine receiver, and indistinguishable from the other as
far as performance is concerned.

One plus of "late" 180A's is that the clock is powered through a plug
arrangement rather than being hardwired in (if you have a "C" version).  Can
make disassembly a bit easier, if needed.

And the "A" tends to be more expensive.
