15VDC vx. 12.6VDC Power Supply

John AC4CA

I was doing some troubleshooting for an inoperative SAL-30 recently when I discovered the voltage at the combiner PCB is only 9.9VDC under load. It is 12.6VDC at the unplugged RG-6.  Although the preamp and combiner have worked fine up to this time, the long run (300+ ft) of RG-6 and its one barrel-splice may have deteriorated over the past 8 years. Would a 15VDC wall wart plug directly into the controller? Can it handle the higher voltages? Thanks. John  AC4CA
