My Friends S-38 was either the C or D model, I got the E model in 1958.

I'm not familiar with the HA-24 RF AMP, I'll hafta go look through my
collection of Heath catalogs to refresh my memory.
Later: I looked through several Heathkit catalog issues but never seen
mention of either the HA-24 or the HP-24, guess I will have to go to
a Search Site to find out.

When I read about your 872B problem I was 'thinking' the tube was a
Triode or Tetrode and couldn't find any info on it while rambling thru
the Transmitting Tubes pages in the back of my 1976 A.R.R.L. Radio
Amateur's Handbook.
So I flipped a few pages towards the front of the book and located the
page in the Index To Vacuum Tube Types for the 872A/872 and learned that
the tube is a Rectifier.

Wow! that 872B can handle 1 1/4 Amps of Current MAX at 10,000 Volts!

I remember seeing the RCA ad on the back of QST issues for their 3B28
Xenon Gas Rectifier tube and suggesting to a Ham Friend to try putting
Two of those in his Viking Valiant TX, since Two different times he had
to replace both 4-Pin Tube Sockets on the chassis for the 866 Rectifier
Tubes because of them arcing over, and maybe (???) having to replace
the 866 tubes(???).

Even though the 3B28's costs several times more than 866's did, he put
them in and those tubes solved his problems.

If there is any Xenon Gas Rectifier Tubes simular to the 872B MV tube,
like the 3B28 is to the MV 866's, I'd think that would be something to
consider.

There I go thinking again, years ago when I learned to type while I was
in the Navy I thought the underscore looked better since it was on the
same level as the period was when I typed them on a sheet of paper.

In a later message either from You or Roy I was able to see the
difference in the small gap between two hyphens and two underscores
typed together.
There IS A Difference!  but you know how it is with the old saying that
it's hard to learn an old dog a new trick.

Speaking of "locationally challenged", Your mention of being in Finland
when You went into the Army, made me wonder if You are Finnish and
moved to Ahvenanmaa?
