Need schematic for a PNI Varmit

[Reg]

I just acquired a PNI Varmit detector that is a BFO/TR. I got it working but I really would like to see a schematic. Actually, this detector works pretty well but would like to try a couple of tricks. More importantly, I would like to see just what they are doing. They are using a BFO coil so how is the TR mode working?

Anyway, I really could use a schematic for this detector. So, if you have a schematic, I would appreciate a copy.

Hi Reg, is this model named Varmit or Varmint?

Probably the same circuit is to find in their model Rebel.

Rebel ( TR/BFO ) - introduced 1976 ? ( per catalog )
Varmint ( TR/BFO ) - introduced 1976 ? ( per catalog )

The control box has the word Varmit.
