I have no idea what it was meant to do, but liked the knobs and switches, anybody know what it's for? LOL

More clutter to accommodate!

I don't know what it's for, but I suffer from "knob and switch disease" too.  S'why I bought this:

That's a cool looking machine, Bingster.  Are those green-eye tubes, similar to what's in my 1940 Zenith?

[bingster]

Yep, they're probably the exact same type eye tubes (6E5/6U5).

GPO, I wonder if you have some sort of tone generator?

I think Bingster's unit is an RF Radio Frequency Generator, used to test and align radio and television set reception.

And, yeah, I agree with Bingster, GPO's unit looks like a telephone line transmission tester, which would in part generate tones of different frequencies.

Wow thats some bit of kit Bingster!

Thanks to everyone that replied in thinking its a tone generator, I'll let you know when it turns up.
