Today I started to study Fisher cz-7a pcb's. All wires were pulled out, so i need to figure out how they were connected. Transmit oscillator looks same as in CZ5. Power side looks different, this model have 5 voltage regulators (or this is what i have found at the moment). I still need to figure out where speaker and how GB pot should be connected. GB is propaply going to J4. battery and power switch are connected J3 I think. And coil is going to be connected to L1-connector.
