Re: A&H GL4000 Power Supply issues


A supply that keeps getting repaired and blowing is likely to do so because of a short downstream causing it source too much current. Is it fuses that keep blowing? PSU components? The short can be something as simple as tiny DC decoupling capacitor that's failed with low DC resistance and causing power supply current to shunt to ground. I've seen happen several times with all sorts of electronics. It's a 10 cent part. It's basic circuit trouble shooting 101.
