The Fine Things are Always Hand Made
I just received an order from Antique Electronic Supply.
Just in case anyone is interested, they have some real nice 6K7G tubes in true NOS condition for only $2.38 each. These are JAN military spec. tubes with the RCA logo on them. They look real nice and work just fine.
I also purchased a JAN 6J5WGT to replace my 6J5G which was highly microphonic. The tube I received works nicely and it is also a new condition (NOS) item. This one was made by Sylvania in 1965. I know, it's not exactly like my old Sylvania, but it sure works well.
