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

I'm posting all the close-ups I did but those 2 components I think will need better photo's than these
i think the close-up of those 6 pins may be good if not let me know and tomorrow (its bed time) i'll open the BITG back up and get better photos
