[Swan] Swan 350 117XC power supply and power input cable drawings

[William Shadid]

Jim,

The 117X is the Power Supply alone (mine is a black box) while the 117XC is 
the same thing with the same supply inside of a Speaker Cabinet.

By separate email I will send you a copy of the Swan 500CX manual in PDF 
format. Toward the back is a schematic and details of the 117X supply. If 
you supply is like my 117X and my 117XC you will first need to replace the 
filter capacitors.

I have a 500C and a 500CX. Nice radios!! Keep that 350 and get it on the 
air.

73 and good luck,

-Bill, WA9MXQ
