Default Mystery Power Supply Unit.

This power supply unit was in my former museum collection. I wonder if anyone has any info. I think the chassis may have been from a former piece of kit.

Looking at the 12 pin connector, could it be a 19 set PSU built into some other military chassis?

Oh I know those retaining lugs - but what are they? I can feel the knurled retainer thing tightening on them in a mount...

First reaction is it a PCR PSU?

Hi Cecil, measuring the available voltages at the socket would be a good place to start. Keith’s thought that it might be a 19 set mains PSU I would think is reinforced by the low voltage looking metal rectifier.

Retaining lugs, exactly that. We called them 'hold-downs'. It looks like a standard Air Ministry chassis.

Doesn't look like a PCR one to me; the PCR has a moulded rubber connector.


In the 50th and 60s there were a few commercially produced WS19 mains supplies, some just to power the receiver, other ones powered both Tx And Rx.

Could you have one of those?? I wonder what voltage it provides?

Hi Jim, I agree it looks as it is a home brew power unit for the W.S. No 19. There is a signal strength meter on the front panel and a 12v. relay on the chassis. I haven't done any checks on it and as my collection has now been all dismantled and gone to other museums I am selling off duplicates plus odds and ends on eBay.
