Replace for 303's VCA ?!?

[Vlado Banda]

Hi folks,
* PRELUDE:
I'm deeply into building clone 303, but I'am stick to original schematics
as fly to a windshield (nice one, ha?). I'm reconstruct PCB to fulfill my
needs, 'coz I'am doing it with replacement parts (or even better?).
* PROBLEM:
I cannot find BA 662(a) or his replacement (it's for 303's VCA). I was
thinking to excange 303's VCA with LM 13600 (13700), CEM parts exluded 'coz
it it to hard to find them it this part of world (or not? but this is not
a question). I was also thinking to replace it with some transistors. Any-
thing is possible as long we keep the original sound. I would not survive
to hear my (hard to finish) "original" clone and realize that some cheap
$300 clone sounds better (read - closer to original 303). However with or
without your help it was fun to build that old piece of history. BTW: if
anyone tryed something similar to this, or have an solution for my problem
- best thing is to send me whole VCA schematic as scanned attachment or
via fax (i would call him, of course!). In fact any help will be appreciated,
so HHHEEEEELLLLPPPPPP MMMMMMMMEEEEEEEEE, PPPPPLLLLLLLEEEEEAAAASSEEEE.
Thanks in advance,

P.S. If you didn't build 303 clone yet, you must start now, 'coz it's
     real fun. Seriously.
