Hi Ed. Thanks for the reply.
I did forget to mention that the transformer has quite a few wires coming out of it so I guess several taps - probably for the ranges. Before I dive into the switches / standard components / transformer I think I should check out the detector a bit more. There are two EF91 stages each with an EM34 giving coarse and fine indications. This looks very similar to the detector in the B221 so I have the manual as a guide even if it's not identical.
Investigation of the range/decade switching etc will have to wait until I've got a clear bench.
