I have 2 TRC-449 that had the same issue..very weak RX..you can stick whatever you got osci, generator, whatever and its a bitch to trace back..
These had that typical scratchy RX that triggers me its a filter problem..
And that was it was!
C10, a ceramic cap besides T3, was split open..This cap is related to L5, which controls the 7.8 Mhz mix..
So if you have this issue, check all those disk caps at each coil..
