This was part of my latest auction haul.
I saw at the viewing that the glass was loose and fouling the needle so my first job was to sort that out. I refixed it using PoundLand roofing sealant. This may seem an odd choice but it looked like what had originally been used and I've used it before for such small-scale glazing jobs.
I then put it back together and it seemed to work but I then found that the needle was still catching the glass as I'd pushed it in again while re-assembling it. I've now done a better job on that, knowing that it's worthwhile, and will let it fully harden overnight.
There doesn't seem to be any information about this model on t'inter-web except for a few e-Bay listings. It does seem though that it was originally supplied as a kit which explains why everything inside is well labelled.
The valves are a Cossor (not surprisingly) 12AU7 and a 6AL5. There are no wax or Hunt's capacitors but a couple of electrolytics which may warrant closer examination.
As well as AC and DC voltage it measures resistance so could well prove it's worth, especially as I've yet again left my DMM on all night and flattened its battery.
I'll take some photos when it's back together.
