How did you test the caps? Depending on the method, they can "test" OK and still not work properly in the circuit. I am somewhat evangelical about the electrolytics on the PS board. IMO, they should ALWAYS be replaced with modern caps rated for 105C temperature as preventative maintenance. They can cause STRANGE problems when they fail, including potentially illegal transmissions. Been there, done that. :) 73 -Jim -- Ham Radio NU0C Lincoln, Nebraska, U.S.S.A.
