Yeah, I know about basements and too much electricity. When I was a
kid, I learned that if I played my electric guitar in the basement, I
needed to wear shoes. Without shoes, just touching the strings on the
guitar connected to my amp resulted in quite a shock. Same thing
happened when working on the S-38. I always wear shoes when working
with electricity in my basement. And I use one just one hand, keeping
the other in my pocket. Anyway, still trying to track down why one
radio is more sensitive than the other. Perhaps some of the tubes need
to be replaced.

Swap tubes one at a time starting with the one closest to the
antenna circuit and see if the sensitivity 'moves' with one of the
tube swaps.
I have to admit it's not totally my original idea. Go here, scroll

After replacing questionable resistors, there has been
no change.
