Below is a our small VCA PCB that has the same pinout and size as a 202 but can be built with inverting buffer opamp on board or not and also has up and down control voltage scaler on it so it can replace any 202 type. It also fits direct into auditronic consoles to upgrade there VCA PCB. Takes 1 to 4 x 218* VCA's and has parts so the VCA can run directly on +/-24v to +/-34v.

The GYRAF clone runs on +/- 15V, which is not enough juice for this board.
In any event, the GYRAF VCA chips are the same 7 pin SILs as those on this board, so you'd not gain very much (forgive the pun) compared to just stuffing the GYRAF PCB itself.
I've built a couple of the GYRAFs, and I know others on this forum who have done so as well - if you having any problems, perhaps we can help?
