Well, the final production PCBs are in. I managed to assemble one tonight.

Well, I am definitely going to get a coax-only for home use. I read your manual. Looks great. I have, like, two questions/thoughts....

The board is attached with double-sided tape. I wonder how this will fare over several years in the oft-warm Empeg environment? It looks like there could be room to add 2 small (homebrew?) nylon retaining clips to hold the edges of the board. Thoughts?

The idea of using the "Mic" line as-is to route the coax output sounds appealing. Reduce the Dremel factor. Any issue with the distance that signal travels over an unshielded pair to make the connection to the Mic output? How long before the 0s turn square and the 1s get short?

Soldering wimp that I am, I will probably take this to a local electronics shop for the attachment of the interface cable...
