[Heathkit] sb200/220 fan

Fri, 29 Nov 2002 17:23:00 -0500

Talking about the 3-500's Graphites, besides additional cooling, are there 
any other required mods needed for the graphite tubes in the SB220?

Its also real simple to tear down the fan, clean and relube.
Amazing how well a freshened up one performs.

On the same tack, the stock fan is marginal for graphite plate 3-500's.

Harbach offered a higher speed version that was nice, particularly for
contesting. I dont know if the new owner has continued with it.
