Perhaps it is not functioning correctly. Have you checked the tubes?

Thanks for the tip. It has all NOS tubes from Antique Electronics
Supply that arrived on Saturday!
What would be the expected
(approximate) range of the AVC voltage measured on the 12SA7 converter
tube with a) no antenna and b) a fairly strong local AM station?
Am I looking for a range of 1/2 volt or so or several volts difference
between conditions a) and b)? I wish I had another similar radio here
to compare with mine.
Thanks again

Hi I use a slinky antenna home made but like the antennas sold on
ebay. Its hanging on a hook on my shop door. I do not think I have
$5 invested. A pece of wire a push on connector to fit the slinky
and some pvc pipe to insulate the ends.

I'm new to the group and I'm just wondering what kinds of
antennas (length, electrical arrangement) people have used
with a Hallicrafters radio such as the S38 type (or similar).
Has anyone used a loop antenna with a model such as the S38?
A previous owner an S38 radio suggested an untuned long wire
antenna,
but a 40 ft length of wire seemed to cause a lot of overloading
on mine.
Also, AM is quite noisy (probably local noise) below 800 kHz with
a long wire.
I'm interested in details like lengths and / or electrical
arrangements (dipole,sloper, etc.) that have been used.
I'd welcome hearing anyone's shortwave and AM listening
experiences
with a S38 model.
Thanks
