On the old version it goes to a potential divider, which sets V out, so I presume it's a pot in this case.
I'm pootling away at this in the background, will post again when i have something to report, Andy.

The pads 123 go the original resistor chain of the Sussex, the LR8 just replaces the zener chain.
When I built my version I dumped the resistor chain and connected the 1M from the Mosfet gate to the LR8 output. I then used the pot in the LR8 circuit to set the output volts
Its Peter by the way, not Martin.......
