Well -- I answered my own questions already.
Apparently that empty spot was where the audio transformer T2 used to be.
The 2nd audio - V-8, a 6F6 is still there. These had two outputs, same
as the BC-312's -- one off the first audio for high impedance phones and
another off the 2nd audio feeding the speaker jack. The later units had
a jumper to switch it to run lower impedance phones off the second audio.
I don't see a replacement transformer anywhere, so I don't know what
that 6F6 is doing anymore -- well nothing right now ;-)
Found a download manual -- I forgot the BC-314 was covered in the do-all
BC-312/342 etc. handy-dandy pocket sized manual. Looks familiar -- I
have an original around here somewhere. No, my memory isn't failing --
never was much good.
I should be able to figure out the dynamotor hookups.
Anybody know if there was a mod involving the removal of T2? More
likely, it was borrowed, I suppose. I'll have to contact RCA for a
replacement. Oh, that's right, Thomson in France bought out most of RCA,
GE and so on. I'll email 'em -- heh heh.
