Modest cost DC power supply
So I had Feastrex re-build my NF5x field coil drivers. They look beautiful and aside from a scuff or two on the back of the magnet, which were there before, appear like new. Now I need a recommendation for a decent but affordable linear DC power supply. The factory spec is 4.5v, +/- 0.5v. Any suggestions? I'm retired now, so I cannot spring for the Feastrex supplies that are over $1K.
