[Hallicrafters] Re: Cleaning Tubes

[Kenneth Laine Ketner]

Water only will remove some lettering and some tube labels. Some are
etched into the glass and some are silkscreened on with water soluble
ink. So I have taken to wiping only with a dry bath towel. Sometimes a
little fingertip of water will be needed on a place where there is no
lettering. A few good tight scrubs with the dry towel will make em
shine. Then I have recently been coating the pins (after cleaning with a
small wire brush) with Caig GXL in a fingernail brush applicator bottle.
That stuff really makes the tube pins and sockets more conductive. It
awakened a screwy Halli SR-150 that had other wise been cleaned.
