[Johnson] 866 / Solid state rectifiers

Thu, 21 Feb 2002 15:34:47 -0800

Same old stuff. You taking care of the old Val, thank goodness. Not
enough of those to go around but plent to break. Been of the BA
stuff. My last resto was an Eddystone 840A. I'm going to have to get
the article out to Barry one of these days. I can't believe there are
folks still wanting to "power" their rigs using 3B28's. Oh well. Cal.
