[R-390] FL-101 replacement Corcom IEC power Filters FURTHER

[Jbrannig at verizon.net]

Or how my '67 EAC ate my printer....

Decades ago the AEA PK-232 offered a FAX capability.
A special cable connected the PK-232 to a dot-matrix printer, an RS-232 
cable to the computer (DOS) and an audio cable from a receiver.
My new R-390A was perfect for this task.  It sat on one frequency all day 
and AP wirephotos would slowly appear on the dot-matrix printer...really 
neat...

At some point my printer died....after trying everything, I took it to a 
local "printer repair" place.  The tech told me "the electronics were fried"

At some point in all this troubleshooting I discovered that the 390 chassis 
was "hot" with AC and that probably fried my printer.

The receiver has been properly grounded since that time and there have been 
no more "issues"

I would also add that the specs state 125VAC leakage current to ground -
2uA.

Hipot line to ground (one minute) 2250VDC
Hipot line to line (one minute) 1450VDC

That would seem to be far more than adequate!

I downloaded their Catalog: 1654001, Issue date 06.2011.

The title is "Highest Performance RFI Filters for Medical Equipment".

That would indeed be "Hospital Grade" the last I understood.

You have choices between IEC, lug attachment, or wires extending.

One makes the choice that they wish.

The IEC version has wires coming out to go to the load.  The module
could easily be attached outside on the rear.

Personally, I'd simply take a computer IEC line filter.  If it protects
a computer for hash trash and surges, it would do the same for a receiver.

I see no reason in the world paying top $ for a line filter!

YMMV - My $0.02 worth!
