[1000mp] FP-29 Yaesu Switching Power Supply

[Rob Atkinson]

Gerry,

If all else fails, you can get separate p.s. from Astron for the two 
voltages.  Of course you have to figure out how to wire them to the 
d.c. jack on the rig and you will have two p.s. to deal with but at 
least the rig will be back on with 200 w.
