For the wire that's disconnected.....where in the circuit does the connected end connect to ?

All the above refs. are as per the Trader service sheet 399.

Thanks Lawrence. I will check the V1 , S5, S17 and L28 .

To be honest i don't understand what you mean with the disconnected cable .
The cable starts from the "fidelity, Normal,Bass,Foreign" switch .
I believe it has to do with the "Foreign" position because is the only position where nothing changes when i choose it.
