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!

I don't think you can hear 20-25khz. If you can, you have better ears than me.:)

I agree with Uru975...

I have a lot of CJ gear (for many years) and have always gone to them (Ed) for asking questions/service/parts.

Ed's a great guy to work with and will surely help you. Go to CJ's website and get their #.

Good Luck

Thanks everyone.

I emailed CJ a month or so back and never got a response, so i guess I will call.

The only was I was able to isolate the noise was switching to a speaker I was testing with a lower frequency response all but eliminated the noise.

If the PV-11 has electrolytic capacitors in the power supply, it would be a good idea to replace them if they haven't already been replaced.
