[Hallicrafters] SX-62 recap

[Douglas]

Here's a bit of an update...

After I finished the recap & all the electrolytics, I
went ahead and installed a grounded plug - unit was
already fused. Cleaned up past repairs and sketchy
wiring. Cleaned all the wafers on the band switch,
switches, contacts, etc. and treated with De-Oxit.

The biggest thing I noticed was the amount of marginal
caps this radio had. ALL of the were about 2 seconds
away from blowing out. I don't know what kept them
together. The Black Beauties were split, the paper
ones had the end loose with wax starting to ooze out.
Because of this, I was kind of worried that the audio
transformer was shot, it checked out ok though. So I
went for it. She powered right up, nothing blew-out or
otherwise. One note here, I was working with a manual
and a schematic and checking against what I was
replacing and its position and found one cap
completely out of the circuit it was supposed to be
in.

It works on all the bands - a relief considering what
I read. A bit out of alignment, but not too bad, even
with the crystal calibrator adjuster (it works too).

The only thing left now is to check the resistors, the
tubes and do an alignment. All in all, not a bad
receiver so far that I've seen or heard.

Found some SSB on 80 meters. That was very difficult,
almost impossible to de-modulate, though got very
close to actually understanding something. No matter,
it wasn't designed for that anyway. Definitely needed
a pitch control and a band spread, but the again I
guess we'd be back to the SX-42.

The big pluses for me as well as for others it seem
are; It's loud as all hell, the gigantic "slide-rule"
dial is just about as exotic as you're ever going to
find on an old receiver like this with places listed
that don't exist anymore and just a general pleasure
to cruise around the bands with.

Anyway, I'm probably preaching to the choir.

73,

Douglas
