Re: Best tweak ever?? This may be it

Hi. Schottkys are the real thing!
I have a uggestion: do not replace diodes on the Display power supply. It is a negative supply, usually around 9 Volts, the display will not work at all if you change to schottky diodes, because schottkys have a lower voltage drop than regular diodes.

Also, before tweaking, measure and make a note of DC Volts at the output of all regulated power supplies (LM317, LM337, 78xx or 79xx).
After installing the schottky diodes, if your DMM shows higher or lower voltage on any power suply, go back to the regular diodes.
By higher/lower I mean .1 V off.
Trust me, you will save lots of debugging time.
Good luck
Carlos
