Dual opto resistor?

[Rick C]

I'm in the process of building an envelope filter from General guitar gadgets and I can't seem to find the VTL5C4/2 dual opto resistor unit at my local electronics store.
Also, it calls for a 430k resistor and nobody seems to have those either.

what to do?

Two 220K resistors in series would be fine for the 430K resistor.  Those dual vactrols aren't too common so you'll have to get them online, I have no idea where.  Check mouser and digikey I suppose.

I got mine from http://www.chriselectronics.com.  I just checked and they have a few left.
