[sdiy] ARP style discrete VCO

[Miketina]

Hi everyone!
Desperately seeking a discrete oscillator schematic, I found an old Arp style design which takes the basic saw and pulse circuit and adds triangle and sine waveforms aswell. Well I made a demo of the VCO - most of it works but I cannot get a pulse waveform and there are some inconsistencies in the sine shape. I was wondering whether someone out there would be interested in helping me fix this problem (I'm no wizard at design),point out mistakes and get this design off the ground properly! I have a feeling that the designer never actualy made this design and it was purely for debate or theory. 
Mike
