RE: Cello used a choke in their Performance Amplifier

Posted by e.goewie@hetnet.nl on September 1, 2011 at 07:20:41:
Hello,
I am planning to order the latest virtue amp called the threee as soon as it is available. In the past i did have an hiraga solid state amp with did use 200mh 2.5A 1ohm chokes in the power supply. I wanna try to make a single rail power supply for the three. I did ask some questions on the virtue site but no answers so far.
If i remember correctly the best supply would use 4*12 volts battery to get 55 volts or a 48 volts switching power supply.
I have a transformer that has a secondary winding rated 39 volts at 9 A. Hammond does have some high current chokes but i don't know if they have enough inductance to make a true choke input power supply. I think the current drawn by the amp will not be stable like an hiraga amp. So maybe first a cap after the rectifier. Anyone likes to share some ideas? Greetings, Edward P.s i do have some 400 millihenry 2 A 4.2 ohm chokes but i think their resistance is to high. Hammond has an 150mh 3A and 1 ohm.
