Thanks for the offer Frank. I've acquired a vintage regulator from Dave and it's sat there (waiting for me to pull my finger out).
The LCD clock replacement procedure isn't too bad. Stopped instructions were good. Rev counter needle has to come off (!), dial face, a plastic piece and a few screws behind. I think the main thing is cleanliness and noting the assembly order. Circuitry contacts, conductive pad(s) and LCD clock itself must be pristine. There are also two versions of the LCD clock. v1 and v2, as partworks.de reference them. If you're going to order one, I'd check on their site and identify which one you've got first. I think you can do this by lifting the dial face and having a look underneath. That's what I did, rather than take it all apart.
Having said all that, my new clock from them still has a couple of missing segments. They were good enough to try and help me fix it then decided to send me another new one free of charge to try. That's something else I need to get done!
