replacement hp23 power supply boards

[Allen A Heibeck]

Mike,

I, too, think this is a great idea. The kit is good. But, I
think just the board itself--along with a schematic,
etc,-- would work quite well for those of us who have,
or can easily obtain, the required parts.

The purist might not go for this.  But, when his rig
no longer works, ours will still be on the air!!
