Jim, this is most probably due to current leakage of the line filtering capacitors inside the R-390A AC filter. Long-term solution is to change the line filter to a modern one or re-built the old one. Not connecting the safety GND wire is an UNSAFE solution. The only other "simple" way I can think about is to use an isolation transformer (117V to 117V) to prevent current(s) passing in the GND connection of the GFI.
