[R-390] Power Cords on eBay

[Bill Hawkins]

What a great way to sum up zillions of messages on the subject
of hot sets and leaking capacitors, over the years.

  Ground the set or wear the wet suit.

Ah - the proverbial "hot" chassis.. In this case the operator should remain
isolated at all times from ground. Grease your entire body with insulating
gap filler and don your neoprene wet suit. Next comes the rubber gloves and
those big Mickey Mouse arctic boots that you can inflate. After isolating
yourself, you need to be equalized to the R390's chassis potential.
A #10 solid copper wire from the chassis to a gold foil coved golf ball held
just over the tounge should do the trick. Now you are ready for a night of
listening pleasure.
