How big a toroid is needed for a 10W/ch Class A amp?

Posted by tommytube (A) on November 7, 2005 at 11:05:06

I'm building a JLH69 class A amp with 10W/ch output. I'm looking to have 22 or 24Vac into my circuit regulated down using a 7824. I'm shooting for an Iq of 1 to 2 amps at 24V. What are the good rules of thumb for sizing an appropriate transformer in Volt/Amps. Per channel or for both channels?

Is there really much improvement to be had by going dual mono trannies? Or is one big guy for both channels good enough?

thanks,
Tommytube
