That thing was probably a Dampp-Chaser (with two P's). They were
used in some receivers and in other equipment to keep moisture out. Just
a low power heating element. I don't want to say they are not made any
more because I think I saw one on the web but a search will determine that.

I had a SX-101A a few yrs back. In the process of restoring it I found
that there was a large "Heating" resistor on the underside of the
chasis, the purpose of which is to keep the oscillator at a temp so it
does not drift. It was inop and I could not find a direct replacement.
So, I found smaller heating resistors that I mounted on a copper strip
which I cut to fit the old resistor standoff mounts. It worked all OK,
and no drift! Hope that helps. - alan K9MBQ
