Boxing day isn't for cold turkey, it's for fettling and pottering in the 'lab'.

Right, so having located pin 1, it was a tag strip outside of the RF box, just under the HV regulator valves.

So, with Crystal Check selected and Range set to A, I measure at Pin 1, 112V DC. With range between two ranges, 86V DC.

So, that voltage will need to be considered if I'm going to connect a signal generator to it.
