I picked up this tester but dont have the coresponding chart or manual to figure out which tube to test in any of 131 sockets.. heh.

does anyone know anything about it?

its a "TestMaster" with a logo that appeards to be an E with an M attached to it.

My word, what an amazing tester! Do you think you could have another go at photographing it, but this time use daylight rather than artificial light? Outside on the snow would be ideal.

uhh.. are you serious?

anatech, if you still have the pictures handy of the underside, maybe those will hold him over until i get better pictures tomorrow.

Just plug tubes in until it is full... put 2 black wastebaskets behind it... and tell everyone it is your SE amp!

Absolutely. I've taken cracking photographs in Toronto at this time of year out in the snow. I took all sorts of valve sockets etc out and fiddled about with different lenses until I got the best result. I wore a thick woolly pully and avoided kneeling in the snow. The first rule of good photography is loads of light. Here's an example (taken on two foot of snow and a bit of paper).

lol poo thats an awsome idea.. heh. and i probably have the tube surplus right now to try it.

must.. find.. black round wastebaskets.

cool ecc that is a really detailed photograph. my digital camera isnt the greatest but i'll do what i can with it tomorrow.

Bored, so had a play...

Smak,

I did some googling for ya; can't find smack... diddly... uh... anything.

But you know, this ain't rocket science. I imagine when you get inside you could measure around a bit. Probabl;y a cascade of B+ voltages, plate resitors, heaters and all. You could make up a chart of what each socket represented.

Pretty frustrating when you realize there had to be THOUSANDS of those things around. I swear I used that very model as teen...

Good luck!

BTW, I did get a strange hit at tubedepot.com... might be worth an email to them?

Hell, we found a manual for anatech's 70 year old scope!

Crack that bad boy open... maybe ther is more info inside.

yeah i scoured the net pretty thoughrally myself.

the underside is an empty cavity with exposed wiring to each socket and a calibration module with 4-8 adjusting knobs.

thanks for trying, i will give tube depot a try.
