[Elecraft] radio shack switching power supply

Thu Nov 28 12:53:01 2002

Mike,

A couple of years ago there were quite a few discussions on the small 
3A RS switcher, including which resistors to swap out for varying the 
output voltage. My voltage was high enough, so I didn't have to make 
any changes.

I'd suggest a search on the model number of the RS switcher (I can't 
remember it right now) in the Elecraft archives, starting in 2000.
