John -
Interesting...
According to Drake schematics, ALL R-4A's had the 0B2, and the first thousand R-4B's (S/n 7000 - 7999) had one. S/N 8000 and up did not!
I have seen B's with the hole for the tube cut in the chassis and a copper-plated plate screwed over it.
Are you SURE it's in there?!?!? And is it WIRED?!?!? :-)
Wouldn't be the first time I've seen something out of line with the published schematics, but never THAT far out of sync.
Also, are you sure that's a "C" on the end? Really should be an (R)ed, (G)reen or (B)lue, although one guy told me he had (Y)ellow! What color stripe is on the crystal? (C)hartreuse? :-)
By the way, there were at least four schematics for the "A", and at least three for the "B".

My R-4B has V-11, the OB2 VR tube. The serial number is 13397C. I am the secone owner but bought it directly from the original owner who was a friend and colligue of mine, now unfortunately SK.
