[Hammarlund] Super Pro 210-SX rides again

[Al Parker]

Hi Bob,
    I echo Ken's kudo's, you're doing great.  It's a neat old rcvr.
    A thought on your dead band - the last/first? one I did had a toasted
antenna coil for one band. It was the VLF model, it was the 100-200kc band
on it, but could be any.  It did hear, but very weakly, sounds like yours
is completely silent.  You might do some continuity checking, might find
that, or a loose connection on that neat guillotine bandswitch arrgt.  I
have a neat, old, little, SS, signal(noise actually) injector that I can
poke onto each section of the main tuning capacitor in most radios & track
down dead stages in that area pretty easily.
    I'm sure I've sent you the link to that work b4, but it's:

    just in case.  The recap process is pretty well covered there I think.
I have another to do, in the project queue.
