why the 3080?

All these circuits are briliant. What is the reason thet the 3080 ota is seen so often?
Its hard to get/expensive. Would half a LM13700 work as well in circuits like the VCO1 or UD1?

No need to change any surounding circuitry? Same performance in the vco? I know what to do with the other half...

The next itteration of hte UD-1 board can place a footprint to use this chip instead along side the CA3080 if folks are interested. This way, if they have the LM13700, they can use it. I am working on getting a supply of "cheap" CA/LM 3080 chips so hang tight.

I have got a nice supply of the SN76477 chips and now working on getting cheap XR2206 and the 3080's mentioned about.

When you get a supply of the 3080 OTA, I'm definately interested in some. I need at least 1 for the TH-301 "Cucamonga".

I'd also be interested in cheap XR2206s

Thanks,

Andy

in the part list for VCO-1 it says only 3080 OTA, but if you search
for the complete partname CA3080 you will find plenty on ebay.

You can try looking for "LM3080" also.
