Success. This is verified and sounds absolutely amazing. Some fantastic sounds coming from this one. Everything working as it should. Worked first time i plugged it in as well. I now have another 9 TAPLFO chips to use. Going to build the Liquid Mercury Tap Phaser soon, just got to order VTL5C3/2s from Banzai unless i can substitute with other optocouplers?
I am able to program my own TAPLFOs if anybody in the UK wants some chips programming I will be happy to do it for free if you send me the chips and a self addressed envelope as long as I don't piss anybody off by doing so.
Edit: Used 47n cap for C1 but not tried any others yet.
2nd edit: Also tried 1n, 22n and 100n and found 100n to be best for me.
