Its nice. Was dodos spare machine and I usually test my glass down there by the method: sit beside, talk alot of crap, drink beer and be ready with the tape, marker and scissors when he utters numbers. Now I got it home instead and I had me a crash course. Problem was I didnt remember anything in the morning so we had to do it again by the morning
Today I tested me some 6B4Gs and now some 6N2PEVs. Russkies are harder since theyre not in the book.
It needs some cleaning in the selectors and a socket replacement or two, otherwise it seems to run like the bulldozer it is.

The TW switches are 12-way, ( I think ) for setting up the tube pin config to match the tester. Two of the switch sections are broken and needs to be replaced. Otherwise the tester is fully OK electronically, and I have all the documnetation I need, service manual included, - and a fully equipped service lab at work..
