[Milsurplus] BC-342-J BFO Help Needed

[Joe Connor]

Guys, I need some help and advice for a BC-348-J I'm working on. The link for the manual is below (AN 08-10-112) and the schematic is on pp. 75-76.
My problem is no BFO. With the BFO switch on, the voltages look pretty good, but no BFO. While I was doing the voltage testing, I found that when my probe touches the grid (pin 2) of the 6SR7 (2nd Det/CW Osc.) with the BFO switch on, I get the BFO loud and clear. With the probe on but the BFO switch off, I don't get the BFO tone. 
Any ideas? From the results above, I assume I can rule out the BFO oscillator, the 6SR7 and the BFO switch as the culprits. What else is there?
This receiver is pretty nice. No mods and I have the shock mount, so I'd really like to get it going full blast.
As always, thank you for your help.
