ch, I believe you will find that Elecraft designs are conservative. To use a 15 volt rated capacitor on a 15 volt rail would be foolish. You will find those capacitors rated at 25 or 50 volts. 73, Don W3FPR On 9/4/2017 9:05 PM, Christopher Hoover wrote: I hope you are saying that the

I can answer that one. It is in the equipment manuals. 15V max. Some components are rated at that level. You really don’t want to go too high or you lose a lot of power dissipated in linear voltage regulators inside the equipment. Of course too low and the transmitters can have issues. Things
