Default Re: Decca Navigator Valve Voltmeter Mk II Type No 605

All the relevant components are RS branded, although as I discovered elsewhere on this forum, the rectifier throws back to the earlier Radiospares days.

I'm inclined to agree that this was some kind of "in-house" design and usage so I doubt that I'm going to turn up any documentation anywhere.

I have a question about this kind of instrument: there is a co-ax socket on the front panel labelled "AC Probe". Can anyone suggest what form this probe might have taken? For instance would it have been a simple screened metal pointy thing? Or something more complex with gain and/or attenuation characteristics?
