No there isn't a short I never messed with it I recently blew the fuse in my meter and I haven't been able to get a new one so I can't measure current and I used a full wave bridge and a 14,000 uF capacitor to help filter it a bit, though I honk it's too low of a value to due any real good...

No...it's actually really quiet...I can't hear it if its on the floor and I stand up...

Okay so I built a power supply from an old MOT for my car stereo so i could use it in my room. My question is, is why does the core get really hot after like 10 minutes of use. The primary and secondary windings remain cool to the touch, but the core itself becomes really hot after more than just a few minute of use. What could be causing this?
