Re: HP 5300B Overcurrent
These dual primary voltage transformer sometimes gets damaged if they are accidentally set to 115V and plugged into 230V. I've had several instruments from different manufacturers that have suffered from this type of overload even though the fuse blew (I guess some people just tried with a new fuse one or more times before giving up or realizing that the voltage selector was in the wrong position).
