[R-390] GFI

[gs at oaft.com]

Hello Roy - concerning line filters:

Yes we use 230V AC but most of the time its close to  upper tolerance  
of 239V ! (guess they want to sell more energy - hi).

Had the issue with the filter also on my EK07 . The R390A did the same  
- the GCI tripped. As its a big job
to open the filters and replace faulty Cs I did change to new filters  
found in PC powersupplies.

When one runs more oldies the failure currents are summing up and trip  
the GCI. We have to use 0.03A types.

In the 390A did set the filter inside mounted on a small  
aluminum-board fixed on the bolts of the old filter.
The existing hole is just wide enough to clear the new plug ( standard  
3-pole PC cable). Works fine in all
my boatanchors. ( 51S1, 51J4, KWM2 etc.)
