The cheater plug just makes a two prong plug out of a three prong plug, you can buy them at a hardware store for under a buck. If you try this and it reduces or eliminates the hum, it could be caused by ground loop.
Conrad Johnson PV-14 background noise
Hi.
I noticed a faint background hum caused by my CJ PV-14 (because there is no noise when I turn on the power amp only), it is not obvious but you can hear it when you get really close to the speakers. I have tried a set of new tubes but the noise did not change. Anybody has experience to share?
Thank you!
