Is there a best place to find or make a cheap power supply for a 50
watt mobile radio to use as a base station? Are computer power supply's
good?


I prefer linear power supplies for this size of radio, such as the Astron
RS-12A. Plentiful at hamfest, surplus and eBay.

IF you find an Astron that is broken and is offered to you for free (GRAB
IT) .. its like being handed money !
Astrons are easy to repair (unless transformer failed - very rare), skip the
Pyramids (many models have under rated heat sinks or electrolytic
capacitors)
