[TenTec] Radio Shack 25 amp switching supply?

[Robert & Linda McGraw K4TAX]

It would suit me just fine if those power supplies were purchased and used
elsewhere.  Don't need no stinkin' noise in my neighborhood on 75M or
anywhere else for that matter.  I bet it's a real singing puppy on 160M.

Go getem' fellows.
