ELECTRO D-612T FILTERED D.C. POWER SUPPLY

​

IN CASE YOU'VE EVER WONDERED WHAT THE INSIDE OF THIS POWER SUPPLY LOOKS LIKE, WONDER NO MORE! JUST FOR FUN I MIGHT REVERSE ENGINEER A SCHEMATIC. IT REALLY IS FILTERED.

THE BIG ELECTROLYTIC CAPACITOR IS RATED AT 10,000 MFD. THE AMPROBE DMM IS TESTING IT AT 60 HZ. THE LCR IS SET TO 120 HZ. THE CAPACITOR MEASURES OVER 10,000 MFD IN BOTH CASES. RIPPLE IS VIRTUALLY NON-EXISTANT WITH THIS VINTAGE BEAST SO OBVIOUSLY THE SELENIUM RECTIFIERS ARE STILL GOOD.
