/* Alternate Versions */
There seem to have been one or two alternate versions:
* The photo in the original article showed a different PCB with Gl1 and Gl2 differently arranged. That photo may have been a dummy/prototype. Later adverts are showing the "normal" Gl1/Gl2 arrangement.
* The magazine later released a correction on their letters page which recommended to replace the 5K6 and 10K resistors on the L200 voltage converter - it sounded perfectly reasonable - except that, the DIY project doesn't contain any of that components. The correction (if it wasn't total nonsense) implies that the magazine shipped different PCBs to some people via their mail-order service.
And aside from the "official" Schneiderware supply, one could of course use any other suitable power supply. Nowadays, it would be easiest and cheapest to use an outsorted PC power supply, which provides perfectly regulated +5V, +12V and -12V with more than enough Amperes.
