First of all that is a nice looking console, congrats on your acquisition!!!
What's up with the tube on the Multiplex? did the pins snap or are they just bent?

The 660A is a very underrated amplifier.
Jon; There's a 6GE12A (Eye Tube)on Evilbay fairly cheap, 3-1/2 Andy Jacksons. Phosphors look good too. Then there's the guy who has a 6GE12 and wants 8 BIG BENS! What the Hell?!?!?!??!!?!? I know it's rare as dinosaur scat, but the seller must be insane. I can get a full set of Hen's teeth Cheaper!
Tony; Note the Eyetube. The 6GE12 and 12A were only made a year or 2 in Early 60's and had limited use. Fisher used the 12A in the 62 Futura. and the 12 in the 100R tuner. Once it goes out and there ain't no more original stock you're stuck.
.. It was a Fisher brand 12AX7 made in Germany...
Mmmm....... Tele's!!!
Looks all 3 of them on that Multiplex are Tele's, here's hoping they test well
