Members MrHotMark Posted September 29, 2005 Members Share Posted September 29, 2005 Is there any kind of formula to figure out what DC voltage you would get after rectification of a transformer for a tube amp? Say a transformer has a tap of 325-0-325 into a full wave rectifier then into a capacitor. About what would you expect for DC Voltage? Thanx all.Mark Link to comment Share on other sites More sharing options...

Members KCA NOS Tubes Posted September 29, 2005 Members Share Posted September 29, 2005 Yes, 325 X 1.414 for a silicon diode rectifier. If you're using a tube rectifier you have to subtract somewhere in the range of 20 to 60 volts depending on which rectifier you're using. This voltage drop is in the rectifier spec sheets which are widely available on line. Google "5AR4 specs" for instance. Link to comment Share on other sites More sharing options...
