[Boatanchors] HT-20

[Carl]

Im still looking for one! I already have a HT-18 which is driving a HT-9 for 
now.

That is one strange parasitic suppressor!

Brian,

They're fairly rare, and a very desirable transmitter in my opinion.
Mine was in such bad shape due to years of storage in a humid area that
not a single shaft could be turned, and I ended up having to drill out
both setscrews in each knob!   Before I committed to restoration I
checked out all the iron, thinking that a bad transformer would be a
deal-killer.  But they all checked OK, and other than the normal R and C
replacements, restoration went pretty well.  I did end up having to
replace the two variable caps in the driver stages due to excessive
corrosion that resulted in arcing, but I thought this was a pretty good
testimony to the quality of the design and construction, in light of the
shape it was in when I got it.   My front panel was redone by W3HM when
WØYVA was restoring a couple of HT-20s and with the powder-coat finish
it now looks better than new.   I have it paired with an SX-88 and an
HT-18 VFO and get excellent reports on the air and it's solid as a rock
when putting out 120 watts of carrier.

I put a few pics up when I was working on it:

The HT-20 is basically Hallicrafters version of a Johnson Viking I,
built to co-exist with TV-watching neighbors.   Unless you find major
problems I'd sure restore it!
