I'm running my QMX with home made power supplies that replace the SMPS power controllers, these use two TO220 sized linear regulators.? It all works except that I don't have the power on/off control.
?
I've built this on strip board to fit where the SMPS controllers fitted.
?
The only down sides are that it takes more power and gets a little warm, neither are show stoppers for me
