"Those appear to be components of the CMO. The CMO is a sort of VCO version of the VOX.. a control voltage applied to a varactor can slew the frequency around by a small amount. The CMO was used in the SBG exciter---you have one!
The drawings for AO-103 and -105 are sizes 2 and 8 and haven't been scanned yet. I'll add them to my list of things to get done!"
