You can get any 2164s from cool audio.
As for the vca, I'd suggest the Gilbert multiplier based one, check modulus ezine 5 (it's on the web) for a schematic. You don't need a 3046 as long as you have two matches pairs, but you can get the 3046 in smt still.

I am still having trouble with this VCA design:
It is noisy, and it gets worse as you turn up the gain. I tried
switching to a 2164 design but its no longer available in SMT.
