Thanks for the offer of the manuals, I have PM'ed you my address.

As I said, I've found the 2 part manual in German, so have downloaded that too. I don't read German but can follow the circuit diagrams etc. It does sound like the manual you have in that some stuff is in both parts. Part 1 seems to be the theory of operation/description, part 2 is the repair information.

I wonder if the continuous-run mod ever existed. I was hoping it was just a 'move this wire' sort of thing, but it might well have been that there was going to be a replacement for the reset/reverse PCB. That would be trivial to fit if you had the PCB (so any dealer
could do it) but of course without the PCB or information on what it consisted of it's more work than I intend to do at this stage.
