Hi Guys,
I picked up a valve tester today.
It looks like the brand name is "University" model "TST".
Any info about it and/or a manual would be appreciated if it's floating about.
It would need a bit of work, it's been sitting under a house.

EDIT,,, well nevermind the manual, I just needed the right Google search terms Smile

Good score, Art. Looks like someone has modified it to test later valve types. There are plenty of advertisments for University Graham test equipment in Radio & Hobbies magazines. May be able to work out a date for when these were originally sold.

Kevin Chant has some University test equipment data here: http://www.kevinchant.com/university.html.

The manual I found so far is one model off, but useable as a "user manual" at least.
It has a schematic, but couldn't trust that would be the same of course.
Funny, if the photo is good enough, voltage dial has gone out of spec, and rather than fix it
he wrote the new calibration on a dial with some white paint stuff that is proving difficult to remove.

Yeah Mono, that adapter can stay, his text can go Grin One of the original sockets is missing
on the far right, but I think if I get a socket I can reproduce that socket adapter module thingy.
It definitely has some unique class & style.

I don't believe the socket is missing, It looks like it's a Philips "P" base socket and they're recessed.

Its likely Dulux rather than a paint pen. Paint pen normally has little resistance to circuit board cleaner.

What you have to be careful of is the black, & paint stripper may affect it?

Yes some of the proper black paint has flaked off, so anything harsh I do to the white marks could
easily wreck up the proper markings too.
I've been trying on just one dial where a mishap won't be so bad for the payoff of possibly finding something that works.
Paint stripper is a bit too far I think I'd live with it before trying that.
