Kinda just got stuck into this and found it hard to stop.

I can now verify the vero layout as working.

No changes other than correcting the 6k8 resistor to 68k.
Made a few subs as I had a few parts missing.
22uF used instead of 10uF for the two electros filtering V+ and Vref.
10k log used for Regen, gets quite resonant and peaky enough at max.
100k lin used for Depth with 100k resistor in parallel. Seems to taper nicely enough (before I put the resistor in, the LFO seemed stop LFO'ing from time to time when adjusting the depth?). I'm thinking of doing similar with the Speed pot, just to spread out the higher speeds a bit.
IC's used, lm13700, TL074, TL072
Plan on switching 220k R5 between two values.
I left a few extra rows on the bottom of my board, plus theres that empty space on the bottom left. Might just fit a Mill bypass in there.

Managed to have a short play with it with a clean guitar tone. I'm very pleased, having only ever used phasers on digital multieffects. This is quiet, clean sounding and usable. Will give it a good listen tomorrow with some dirt pedals when I can turn the volume up.
Next on the cards is an addon board with some extra switchable stages (will post layout here) and probably a few tweaks here and there as I get to know it a bit better.
Thanks for a really nice first analog phaser.
