Best thing to do is re-tube,since you have no idea what condition the tubes are in from the last owner..I would take that as your first step..More than likely its a tube at the end of its life.....
Conrad Johnson PV11 Noise Issues
A couple months back I picked up a Conrad Johnson PV11-- I am thrilled with it. It was exactly the sound I was chasing.
After having used it for a while, I am noticing a decent hiss in the 20-25khz+ range. Not having any CJ gear, or a tube pre for that matter, previously-- I lack any context on what the normal noise floor is like on these.
Is what I am experiencing normal? If not, anything specific that needs to be looked at or should I be contacting CJ for a service.
Thanks!
