I downloaded a manual from BAMA for an R-4b but find quite a bit of
difference from the 4b in the BAMA manual and the one I have. The BAMA
version has 10 tubes and mine has 9. I suspect mine is more of a hybrid
version and has a serial number of 9737C.
Any Drake gurus out there that can point me to a source for the correct
manual/schematic for my 9 tuber with the above serial number?

Thanks for reading, Rob Mills

PS, I also have an additional jack with factory marking "spare", The BAMA
version shows an un-marked empty hole there.

The R4-B is advertised as a ten tube receiver,but,tube V6 is not used
,there is no V6,,,there are only nine tubes in use. Receiver is
definately a hybrid ..My schematic does not show V6 at all. If you need
a copy I can have one made for you..Double check your schem and see if
V6 is actually there.. 73 W4PQW

Thanks a lot for the offer but just received some info from Garey at
http://www.k4oah.com/Drake_new2/B_Line.html who sells a CD with a lot of B
line Drake info including manuals which I'm going to order.

the removal of the VR tube and the conversion from bipolar to FET in the
PTO.", my serial # is 9737G.

Thanks for offering to copy (I know that's a lot of trouble) but I'm going
to order the CD, Rob Mills
