I think I was wrong about that black mystery component at the back of pcb. It has in fact 6 pins (see the pic) still no idea what that is but the +/- pins are Vcc and GND. But now it is beginning to look like a VCO. I think the control voltage is probably the single pin on the top that connects to the big through hole resistor Sandra, can you post a close up photo of the rectangular area that I designated on the picture |
