Finally, my beloved Drake R-4C is perfectly working again .

I've found that the third mixer tube (V4) was dead . I wisely checked
the circuit and i've found that the Injection signal cross the tube.

So i checked if my external DDS I used for like ten days could be the
problem and hey ! The output signal was set to +7 dBM ( wich mean
about 5mWatt if i'm right )

Bit too much huh ?

Many thanks to every gentlemen who "directed" me on what to check .
