Hi.
Well the can has had it's chips, although the connection has been made OK the ferrite around the coil is in a sorry state, it was crumbling before my eyes so I didn't hold a lot of hope TBH.
I have good signal to the last IF amp but the level on the collector is far too low and it wont peak up. I do have another IF transformer from an unknown board but it uses an external detector diode so I'll cobble it in on Friday and see if we get the set up and running.
Oh incidentally the motorboating is intermittent, It's caused by the plug to the audio board, possibly a poor soldered connection on the earth wire pushing them or twisting clears the fault.
