fear not, for I have recently took the initiative to draw up a replacement with some improvements(or not) stemming from my fight and subsequent loss with my MK-012s. Yes, the traces have started to come off and so forth.

I haven't etched one yet, but will this week unless anyone spots anything i need to fix.
Some notes..
The JFET footprint is DIFFERENT than the original, this one is for the 2SK170 series. I have also tried to include extra pads for ease of installation of resistors and such. the trace widths are a bit larger and should help keep the traces from coming off the board like they do with the original. I have not measured the lytic caps to see if they will fit yet so that might change soon.. The rest is pretty much the same and there are a few mm at the ends where the cutouts for wiring and the spring socket are. I haven't gotten around to laying those out yet but it shouldn't be too much trouble to cut them out to fit. I also included a boundary line around the board for the maximum size. cutting the board out slightly smaller than that line was the idea.
PM with questions or comments.
