[Vintage-Audio] Cleaning up old equipment

[Duane Fischer, W8DBF]

Lee,

I do not know about tape or video heads, but I have used the one dollar bill 
method on relay contact points for many years. Perhaps the U.S. Mint is 
including 'something' in the bill to foil counterfitters that helps radio 
buffs! Just as either the ink on that business card, or the actual texture 
of the card, work with a video head, perhaps the silk fibers and ? in the 
ink work for the greenback.

Some great ideas Lee, thanks!

P.S. The bass singer you made mention of at RCA Studio B you could not 
recall the name of, was the one with the Jordanaires or J.D. Sumner?
