[ARC5] Availability of SCR-274N/ARC-5 connectors?

[Roger Basford]

Hi Brian,

I had a chuckle at the recording of the dynamotor idea! No, the be honest I 
don't really need the dynamotor and I do have a good selection of mains 
transformers that will do the job, for both TX and RX.

Have you made your own connectors at any time? I had reasonable success with 
the RX and TX male connectors using car body filler and pins from QM plugs, 
potting the whole thing in a old octal valve base with the wires exiting 
where the valve pins used to be. Not pretty but functional and a good fit 
into the sockets on the gear. Anyway, all ideas gratefully received! I'll 
have a look at the Apex site but I bet they've long since sold any 
connectors on eBay, where they fetch more than the radios!

73,

Roger/G3VKM
