First of all, a bit of good news : The RT7 does not have the AF11x problem.

The circuit is available up top there. You're getting power otherwise you wouldn't hear a plonk when you switch on.

So - Clean the wavechange switches, check all wiring. Can you put a signal in at the Volume Control? A CD player will do - earth to earth, other wire in at the centre pin of R23. (Volume Control).

If it seems OK, then you really need some test gear - a Multimeter at least. If there is no sound, I would go for TR6 and TR7.

Cheers,

Steve P.
