[Elecraft] KPA500 Hum

[Johnny Siu]

Hello Arie,
 
There has been additional new hardwares in the installation of the transformer as in the latest KPA500 kit construction manual.
 
I have solved the hum problem by trying another transformer tap and installing the new hardwares.

TNX & 73,

Hope there comes a hardware mod to obtain minimum hum.
