[Boatanchors] HX-50 UPDATE

[Carl]

It takes skill, eyesight, and something besides shaky hammy hambone hands to 
work on them.

Besides if it is already sluggish or dead it is ripe for taking a shot. Ive 
had fair luck at rejeuvanating them and only broke them early on practicing 
with $1 a dozen hamfest CB rocks.
