Ron,
OK, thanks! I still have not inspected the chassis in
that area so now it should make sense to me
when I do so.
One other strange thing I noticed about this radio
is that the RC parts #7,#12, and #17 appear to be
fed the B+ from the opposite end of the string
compared to the schematic!
The schematic shows the B+ coming in at point "D"
which is also the feed to the output transformer
primary.
My chassis was wired so the B+ comes in at the first
RF tube and then daisy chains to 2nd RF, then 3rd RF
then the transformer primary!
Strange. This was all original wiring I'm sure also.
I am wondering when I re-do this that I should make
it like the schematic ?
