well it would make sense like I said the tube socket itself appears to have a bad case of Cadmium Corrosion and I don't know how that would affect the tube socket itself and its ability to allow it to make contact between the socket and the tube. and yes the tube is a known good tube, in fact its a NOS Tung-Sol 12AX7 tube that I had found in an old tube caddy someone gave me that was full of NOS tubes of various brands.

And how could a 12 volt tube still work even with only 6 Volts on the heater pins? wouldn't that cause the tube not to glow or barely glow?
