There was someone on the list that replaced this old filter that WILL 
trip a GFCI with an IEC, (Computer type) receptacle on the rear.

These are MUCH better than trying to simply replace a known issue with 
the same problem again.

IECs can be scavenged from any old computer power supply.  The only 
thing to look at making sure you take with it are the X Y Safety capacitors.
