.. I have had an S-38 on the shelf for a few years and
finally got
around to recapping it this weekend. All went well and it
does play
but not as well as I figure it should. I did find one loose
wire that
is attached to S1B terminal “O” and goes nowhere. There is
another
lead attached to that same terminal which goes to the
antenna terminal
lug 4. I don’t see this extra lead on the circuit diagram
and it does
appear to be a lead that was there when the rig was built.
It look
like a cream colored lead with red stripes. I wonder if
anyone has
any idea where this lead is supposed to go? I

Karl sent me a photo via private e-mail. I opened and
looked at my S-38 and it does not have the wire he
indicated. The wire goes from the antenna tank section of
the bandswitch to the RF grid of the converter tube. The
schematics do not show any other connection to this point
nor is there any sign of on in my RX. I can only speculate
as to why this wire was added. Hallicrafters made almost
continuous changes in the details of their receivers so its
possible this is a factory job but I doubt it.
My S-38 is evidently a late one because the cabinet is
finished in black wrinkle rather than the earlier black
satin finish.
