Question for the Masters
So, I picked up a huge lot of tubes and other assorted electronic bits not too long ago. Not a lot of useful items, but always interesting to look through. Among the items I found a most interesting little doodad. It's wafer, about the 1 inch in diameter. It looks like it's made of some sort of waferboard, like an old clipboard. Out one side, a 9-pin tube 'base', like the bottom of a 12AX7. On the other side of the 'coin', the leads converge into a very small metal 'cap', definitely smaller than the ring created by the pins on the other side. Printed on the cap is what looks like:
ECC705A
7041
Any thoughts?
(I managed to get 1 half decent picture of the thing, but I can't figger out how to attach it...I'm kinda dense that way([/img]
