[Hallicrafters] HT-40 Polarized Plug

[Bill Barfield]

I finally got my HT-40 working. I changed out the paper and electrolytic
caps in it.  The chirp problem turned out to be crystal problems. It sounds
fine with a VFO.

However, I have noticed that I have about 45vac worth of hot chassis voltag
over ground. I suspect that the bypass caps in the power supply may be a
little leaky. I'd like to put in a proper polarized and grounded plug. But I
want to be sure I do it right.

As it is currently wired, each side of the non-polarized input goes through
an RFC and are then bypassed to ground through a .001mf cap. One side goes
through an SPST switch and then connects to the power transformer
primary.The other side has the same RFC and bypass cap arrangement, but then
connects directly to the transformer primary.

If I wire this thing the way I think I should, I should remove the bypass
caps from the primary side of the transformer and leave the RFCs in place.
The hot side of the polarized plug whould go to the input leg with the
switch, with the neurtral going to the other. The ground leg, of course,
goes to the chassis ground. Does this sound like it would work?

This hot chassis problem has created a weird effect. If I tune my antenna
using my IC735 as the signal source, I can easily get a good SWR. But if I
switch that same antenna to the HT-40, I get a very high SWR. I think my hot
chassis is making the SWR meter false. I get the same effect with the dummy
load.

Any thoughts or suggestions?
