[Eliot Ness]

If you have voltage on the plate of 6K7 (RF) and the plate of 6K7 (IF) then something must be wired incorrectly.  Check both sides of the IF (#10) for voltage.  Then check at R23 and then the junction of R8 & R7.  If you have voltage at the resistors but none on either side of the IF (#10) then it isn't connected to where it should be. 

In-other-words, if you have voltage at point A and B but not C, then there must be a disconnect between point C and D.
