Hello, all and Happy Field Day. Say I just wanted to comment about Elecraft service and the help they provided me to make a mod to my KPA1500. My KPA1500 power supply fan was rather noisy. I had seen discussion on the reflector about this so I contacted Doug at Elecraft service. He ask if I could solder. I informed him I could and he sent me a new 22 ohm, 3 watt resistor and i swapped it out with the 10 ohm, 3 watt resistor on the LED board of the power supply. I am much pleased with the sound of the power supply fan now after the modification. My amp is an early serial number and the new amps come with the 22 ohm resistor on the LED board. So...if your power supply is a bit noisy you might consider this mod and contact Doug at Elecraft Service. The Elecraft part number of the resistor is E500128. 73, Steve W0SZ. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net
