Re: quad 303 power supply schottky diodes

Hello,

Why the specials? Use a modern bridge rectifier with a high forward
current, designed to drive high value capacitors. With 50 or 60 Hz
you don't need that speed.

It's not about the speed, it's about the much sharper cut-off of a Schottky diode, which generates much less RF crap than a normal rectifier diode....

The most important component in the power-supply is the capacitor. Dada uses BHC Aerovox or Nichicon in Quad 303, 405 or 606. Apart from the capacitance and...

The quality of the DC power depends on the quality of the capacitor. Any good rectifier bridge will do the job in a 303 if you use a high- quality capacitor...
