[R-390] Line Filter and R390 IF strip

[Bill Hawkins]

Rodney Bunt said,
"The bypass capacitors on the mains go leaky and you are fealing this."

I say again, a bypass capacitor with infinite resistance (no leakage)
will give the same tingle. There Is No Leak. Nothing is wrong, except
that you, the operator, have not grounded the receiver. You did read
the installation manual, right?

A capacitor of 0.1 mfd has a reactance of 27K Ohms at 60 Hz. You will
get the same tingle if you hold one end of a 27K Ohm resistor with a
dry hand and touch the other end to a hot mains lead.

There were no ground fault interrupters being made when the R-390 class
of equipment was designed. Do Not Use A GFI. Rely instead on the good
ground that you have used for the radio.

But if the bloody GFI is built into the power entrance panel, then you
must either use an isolation transformer or disconnect the filter. It
will not help to replace the capacitors.
