I found the link, but you need to be a forum member to download the images and schematics. There's quite a lengthy thread there.

Quite a few being built in the UK, my latest circuit is on the link below where I have added a low heater voltage regulator for testing battery valves and a heat sink fan.
Also combined the whole circuit together, I think it is better to download the image and view in MS Paint.
Still in the process of metal bashing. You only have to 'free' register on the Forum to get full access to it.

Notice I added a 50 way D connector to the PCB for easy servicing and the circuit shows the pins I chose for the various functions and signal paths.

Also may I add that I believe the circuit boards and transformers are still available from the Forum members responsible for having them manufactured. The transformers can be supplied with primary voltage for the States. Note that the custom transformer has three separate and thus isolated meter supply outputs for powering the low cost AC powered LCD panel meters as mentioned on the Forum.

Hi-Q, Has there been any revisions made to the pcb layout to facilitate changes ? If so could you post a picture ? I have ordered a transformer but decided to wait on the pcb till all mods or additions are final.
