Problem with Boxford TCL lenze controller

[Doddy]

Hi doddy
I killed that board a while ago , Cant remember what I did to it. Maybe it was when I blew up the 12v PSU
I seem to have blown up more things than Blaster Bates.

I was biting my tongue to not comment on that :)

Is there a cheap replacement out there? (I have ancestors from yorkshire) or do you want to see if you can revive this board again

It's easy to say - that you should be able to source a standalone charge-pump circuit, but I did struggle to find a UK source given a couple of google searches. I'm sure they're still available somewhere. It does make a bit of a hash of your cabinet with spurious boards... but I think that you're not afraid of that.

Happy to look at your old board, though there comes a time when you just have to let go!, if it does float my way then I think this time I will recover that 12V on board supply despite your earlier protestations. Alternatively I might knock up a few charge-pump relay boards - if/when I get roundtuit I could throw a couple in the post. But there's a timeline for that which involves china.
