There's even a 12pt-6pt variant with the calibrator lead, for use with sets modified to run from the later (Canadian No.2, British twin dynamotor, Eicor dynamotor, or the AC Supply Unit Rectifier No.1) supply units.
Other variant power supply to set cables include the RF Amplifier No.2 control cable (with HT2 brought out to a 2-pin socket so that the amplifier control relay can be inserted in series) - which again exists in 6-6, 12-6 and 12-12 variants, and a _very_ confusing to the unwary 12-12 lookalike that has the 2-pin socket connected to the +12-volt set (valve heaters and relay) supply and ground - this was for running the Power Supply and L.F. Amplifier units (1, 2 or 3) for the WS38, 88 or 31 AFV variants in AFVs - usually in conjunction with the Canadian Supply Unit No.2 to provide 12V from a 2-wire 24 volt supply in later tanks. (If you try using that particular cable on the RF amplifier it switches the amplifier to 'Send' and it stays there - the 12V won't damage the control relay but seriously confuses the owner!)
Best regards,
Chris.
