OBERHEIM SYNTH

Ok hard-core synth builders out there...

I have an OB-X the uses CA3080 VCA's like they were going out of style, 
which unfortunately turned out to be the case.  I need a replacement 
CA3080 for a mod I want to do (make the noise level 
programmable/adjustable if you are interested) and I am seeking an 
alternative VCA that will work like a CA3080, but that is more easily 
available.  The VCA does not need to be pin compatible with a CA3080 
(but it would be nice).

Any suggestions for a replacement/alternative part?  If so, where do I 
buy it? I only need 1 or so VCA, not 50 like I see on e-bay. Anyone 
have some 3080's for sale? 

I didn't have much luck on Mouser, Digikey had some possible parts but 
they were non-stock and about $20 per chip.   

Thanks in advance for any suggestions.

futurlec.com has/had them. They just went to $1.50 from $0.80 or so. NTE had (past tense) a replacement that was discontinued a month or two ago. Steve ... --

Thanks for the tips on the 3080!!!  It looks like the RCA's are
out-of-stock but I can get the a replacment parts for about $1.50 -
that is great news.  Thanks again guys for the tip.
