''That's very funny. It's not a rare thing or anything, but you have (one of) THE classic bits of test gear. Like someone apologising for ignorance of wrist watches and then pulling something out of a draw and saying 'it appears to be Swiss - Rulex? Ralex?' ''
I'm a collector, I even have some old classic radios. Apart from my computer, the most modern commodity I own is a 1920's Bergere suite
I've now replaced the soldering on the winding to cord wires with connectors and taken fresh readings with my digital volt meter, I have constant readings of 22.5 between the grey and green wires/grey and black wires. No registering on anything between the brown wires with everything else wildly flashing and fluctuating.
The brown wire I have attached to the brown/white striped wire from the winding. I'm presuming this is a live wire.
