Default "Sony Air 7" squelch replacement

Hello,

I have a little sony air 7 radio that is working nicely.
The volume pot was defective so I have replaced it with a new one.
Unfortunately the squelch is now dead. This potentiometer is a little special as it has an auto and manual feature (pot can be both turned and pressed up and down) I am simply unable to locate the same pot or anything like it. The best I have come up with is a pot with the same resistance but it only has three pins. The original pot has 8 pins (if I remember correctly) When I solder the new pot on, the sound is dead entirely.

So for now the only way I have been able to keep the radio alive was to solder a 100k resistor to two points which seems to bypass the dead squelch and enable the volume to work independently.

Does anybody have a clue how I could use the three pin pot?
