Does anyone have a source for ca3096 or part # of an equivalent npn/pnp transistor array? I want to build the Steiner VCF. (http://www-timc.imag.fr/Yves.Usson/personnel/SDIY/Modular/Commun/STEINERVCF/VCF-schema-CA3096.jpg)
Is there a synth-oriented newsgroup out there?
Thanks.
Jason, this may be a tough find. Digi-Key has the ca3096 listed but it is not in stock http://www.digikey.com/ still, it's a reasonable price if it is still there. Also, Circuit Specialists carries a ca3046 - I'm not sure if this will work or not - http://www.web-tronics.com/ and Mouser carries the NTE replacemnt for the 3046. Good luck

Thanks AL!
ca3046 is a npn array, ca3096 has npn and pnp transistors in one package. I was hoping that someone would have one that they would wish to trade. :wink:
Also, I am just thinking aloud here:
Do Q3 and Q4 need to be matched in any way?
I have ca3086, could I use 2n3906 along with it?
I will breadboard the circuit, but I wanted to ask the forum first.
Thanks.
Q3 qnd Q4 don't need to be matched. However, I think R15 and R16 may need to be tweaked with different transistors for best performance.
Or Q3 and Q4 could be replaced with a non-inverting op amp.
Thanks Tim! I'll do both and let everyone know what I think.

there certainly is!
