[Elecraft] power supply

Fri Nov 1 12:52:01 2002

Speaking of linears, a while back someone posted their recommendation for a
'surplus' high current HP linear power supply. I can't find the post but I
sure would like to know the model number of that HP.

I'm thinking of getting one nice big fat linear and hooking it up to a
Rigrunner so I can completely convert all my gear (including the dinky
stuff) to Anderson powerpoles.
