Yes- retube! Be certain that whatever tubes you buy are certified/graded as, "preamp/phono/low noise", "gold" or "Platinum" by a reputable and knowledgeable dealer. ie: (http://www.upscaleaudio.com/pages/Testing-Small-Signal-Tubes.html)
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!
