Sv: Re: [sdiy] Top DIY VCO

[Daniel Araya]

Check out the SAS-VCO/ASM1-VCO at http://www.jacek.nu/sas/vco_schema.pdf 
Works really good and all components are easy to get, with only two components being "not so cheap": the tempco-resistor and the Analog Devices MAT02 transistor pair. Tempcos can usually be bought from other listmembers and the MAT02 can (could?) be had as a free sample from www.analog.com.
I have ten of these oscillators.

Hello all,

Thanks for your comments  ;-)
Ok for using several VCO instead one for fatness.

About discret componants:
I didn't understood 'discret', I don't want to use expensive or too 
exotics chips as CEM. I just want easy to find componants : )

So, I got only 3 links,

MOTM-310 kit n@ www.synthtech.com 
ARP 2600 VCO
Ray wilson VCO

Nothing else ? what's about Rene Schmitz's one ? Some are more 
recommended than other ones?

thanks
fred
