A contact in Germany has the complete service manual & schematic that
he is xeroxing for me which should help considerably..

There remains only one tube to be found & I have 4 vendors looking for
the US equivilent if not the exact replacement tube. ( ECC85 )

ECC85? Ouch. $15 at AES, and they're out of stock. As far as I know, the
ECC85 was never used in any American product, but there's plenty of tubes
with similiar bases.

If you can get a chance to rummage through a box of tube pulls, you will
almost certainly find a few 6BQ7s and 6BZ7s. One r the other of these was
used in almost every TV tuner of the late 50s to early 60s. The only worry
is the plate voltage rating on the 6BQ7 and 6BZ7 is lower than the ECC85..
I know I'd try it, but I've got alot of old pulls just sitting in boxes.

I wouldn't buy a new tube that wasn't an exact replacement, but maybe one of
your vendors has a reasonable used sub for about fifty cents or a buck and
can put it in with the order.
