audioguru Posted November 29, 2009 Report Share Posted November 29, 2009 I have 60VA transformator (230 / 22VAC - 2,8A). Is that enough for original regulated power supply ( here )? How many ampers fuse I need for that transoformator on primar side?Thanks. A 22V transformer will allow a 23VDC output at max current. Use a bigger main filter capacitor because the original one is much too small.a 2.8A transformer will be overloaded when the output of the project is more than 2ADC.
