Hi all.
Built up a copy of the DC supply that was in a old Micor manual. Used the caps and filter choke from an old supply. Add a LM 317 with heat sink. Added MOV's and additional hf caps. Seemed to work fine. This fed a full micor repeater with all the normal modules. Worst case 9.6 volts current was about .75 amps. Have this on a repeater up in Montana.

How about a 7809 regulator IC with a 1N4004 diode in the ground leg to raise the output voltage to 9.6V? > I was envisioning mounting it to something metal for heatsinking purposes, > but I guess you could probably use one of the screws on the backplane plus a > little TO220 heat sink.
