I hope this is not a double post, but I've waited 8 hours and have seen
nothing.

Fred mentioned on his first post that the dynamotors had been removed
from his two 18S units.
When I saw illustrations in this instruction manual, the first thing I
saw in a top view of the unit were the 811's and mod transformer. They
certainly appear to be lifted from an ART-13 as well.

It's been a long time ago, but my father told me about the 18S receiver
and the fact that only 28 volts were used on the plates and screens. I
was just a kid of 9 or 10 years old. Even back then I knew that most
radios needed a hundred volts or so. Even the "All American Five"
series string AC/DC sets had better than 100 volts B+.
