Many thank, K3HVG, but I have this one, viz:
"Maintenance manual for BC-348-J, N, Q. rev. 21 June 1948."
...but it is for models J, N and Q only.
The "R" has a different tube line-up (see my OP).
Cheers,

As K3HVG *correctly* noted - the BAMA site has the schematic for the R
(as well as the others). For most purposes - any schematic that
includes the 991 tube (which isn't in your list) will be usable for the R.
