The mains input transformer has an open circuit primary winding (and I've been unable to readily source a replacement Tx ... or, if you prefer, trafo). smile

But I'll be sure to check out what you are saying the next chance I get!

But (regarding your last post) I should be interested in hearing more about what you are able to do (services on offer, whatever).

For instance, we may be interested in packing up the odd box of "junk boards" (of many and various types and sources) and sending them out for you to have a go at. Respond by PM if you prefer.

If you don't inspect ... don't expect.
