[Racal] Schematic/Circuit Diagram for RA121 and RA237

[Nick van Stigt]

Hi,

Does anyone have a copy of the schematic for an RA121 (ISB adaptor)? 
  Either a scanned pdf or hard/photo copy would be great.  I'd be happy 
to pay the expenses incurred in either case.

In the case of the RA237, I only have a schematic for a RA137 to go on 
at present.   I understand that these models are almost the same, except 
that the RA237 has a post-mixer filter so it can be used with a RA117. 
   If anyone would be prepared to  photocopy/scan the RA237 schematic or 
even a manual I'd be happy to pay them for it.

Thanks and 73,
