Right you are. Live and learn (even at 81), and I even learned a new word -'vias.' Thanks.

@alexsh1 If the pinout is the same, then the PCB should work.

Thanks you a lot for your work

@Marcel-Stör Sorry, I don't know. Maybe try the datasheet.

@NeverDie Perhaps but the design is a bit too simple and unoriginal. I'd have to clean up the files a bit and I haven't touched Eagle since I made this board several years ago.

@soward I use some sort of no-name 10 uH 12mm (I know, stupidly big) shielded inductor from AliExpress. Looks a lot like these, fairly bulky and heavy: http://m2.uxcell.com/photo_new/20140506/c/ux_a14050600ux0992_ux_c.jpg Haven't done more than go over it with the continuity tester to see that it didn't have some sort of rudimentary inside damage. I also tested the capacitors, they were close enough to 10 uF but I did some surprising minor variation that can't be blamed on the DMM. Random Ebay caps are probably not a good idea if you need spot on values. But they did seem to work.
