Since any significant problems in the 7A13 will cause gross

ohm coaxial cable.
Some interesting stuff coming out here, as usual. Here's some preliminary results with the relay adapters in place -
I haven't got stuck into it properly just yet. I'd like to know what the pulse generator's doing first but that's what it looks like so far as it is. I've replaced k60 and 61, one of which was bad but it seemed sensible to keep them matched and K47 and 48 (both bad). I've since got some more attenuators which will allow me to check the lower ranges but haven't tried them yet. I managed to rejuvenate one of the relays but don't really trust it. The fact that it's recovered suggests it's knocked the flaking crap off the polepieces which is now floating about inside the case.
