Default Re: Quad FM1 questions

Sorry guys here we go again.
Managed to sort out quad2 pre amp still bit of a mystery but I'm back on this FM quad tuner. This model I think is their 1st version so the schematics I can only get on lineare for the 2nd model.
Does anyone have the schematics for my model? Be great help as I'm working blind. Have attached pics of base and schematic I have as you can see completely different.
The other thing the hunts 8uf electrolytic cap is can negative. Now I opened up the can and put in a new cap with negative soldered to the can. But radio does not work just a hiss. I also tried soldering negative to chassis ground and still the same. On schematic it looks like negative is going to the top mounted 5k resistor which goes to pin 4 on HT lead. But original can has no such physical connection.

Any pointers most welcome.

Cheers Chris
