Nice work, Lee,... sounds as if you are getting there..Can I ask, did you buy a kit of parts, or did you get the components yourself??? The reason I ask is I sourced my own parts, and had exactly the same thing at power on, low negative volts, and it turned out to be the 4066, It needs to be a Cmos type, I had a 74HC4066, and it didnt like the plus 8, minus 6 volt supply range.
Its easy to test if you have used sockets, just unplug the 4066, power up, and test the minus 6v line with it out.
Best of luck with it, have fun, Fred (in Mansfield, 6.00 am, minus 6 C, and missing the sun!!!)
Cheers, Fred
(oh, and the negative supply is dependant on your oscillator, and therefore coil, can you check it is running somewhere near 14 Kcs????)
