[Hallicrafters] Re: SX101A Converter Subchassis

[Mark K3MSB]

Well, got that little project taken care of.   Not that bad removing
the subchassis (now that I've done it......).    A buddy was down for
a few days (KB9MW, another guy that likes to dabble in tube gear), and
it was mighty nice having a second set of hands around.

Now to replace the resistors (as needed) and the BB's on the
selectivity switch, and my 101A will be completely recapped!!

I might mention that my 101A manual does state some of the caps are
molded paper, C208, C209 and C210.   I wonder if some of you can check
yer manuals to see if they're different.  I'd be interested in knowing
when Hallicrafters changed over to disc ceramic caps;  or maybe they
always did and the manual has a few typos!
