Hi Eric,  Ay-yi-yi, too many pin 6's, too many 12BA6's!  I'm presuming that you are referring to pin 6 on the 1st IF 12BA6 which connects to the 2nd IF can at the .002 cap, because pin 6 of the 2nd IF 12BA6 connects to the 3rd IF can.  No matter, re-check your ground connections between the 1st IF and the 3rd IF, and the both 12BA6 tube sockets and surrounding wires for continuity.  Keep us informed!  Joe
