OK with the 100pF cap in place and signal injected on pin 6 of 1LC6 I do hear faint tone. I'm pretty sure its due to the signal since it disappears when I switch off modulation. Guess that means that the 2nd IF transformer 47k resistor is kaput or there's something else wrong in it. If that's the case, I'll have to study it a bit to see how best to get that off, opened and repaired.
