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!

If you want super quiet, get a solid state preamp. My C-J PV5 has some noise too. But I have to stand real close to my speakers (6"). If you can't hear it at your chair, don't worry about it.

I just purchased a PV14L from an A-gon member and this unit has no hum at all. The unit came with a total of 4 tubes and 2 of those had tube hiss but after sorting through the tubes I came up with 2 that are nice and quiet. You may want to try a cheater plug and see if that removes the hum.

Jeq, Did you buy your tubes from CJ?
