[Elecraft] CORRECTION Re: SB-221 for K3 need some help.

[Don Rasmussen]

Oh - by the way - my Sb-221 bandswitch is in a
shambles but I hard wired the amp for 20 meters until
a new switch arrives. I learned a valuable lesson,
bandswitches are delicate, close tolerance devices -
don't ever try to repair one that is cracked - hi -
but the contacts can be replaced if the wafer is good.

Time was, I would never consider working on an amp -
too intimidating. But after a couple K2's, soldering
up those big anough to fit in your hands parts seemed
to be a piece of cake!!!
