Hi Patrick,

I have an Io also. It is about 5 years old. My Io is noisy (tube rush) but not what you are describing. Based on my experience with the Io, the citical tubes are V1 and V2. You already know this.

Take a look at this link:

I am wondering if this is the issue with your Io.

Have you tried swapping tubes out in the power supply?

If you have a tube tester, it may be time to check out all the tubes.

Hi guys, my Io has the latest resistors, so that isn't the problem.

I haven't tried swapping the PS tubes... no EL34s lying around (or rather there are some, but I'm not sure how good they are). No tube tester either :-(

Patrick, it definitely sound like RF. I bet if you placed the Io somewhere else it would not be affected by the RF. I don't think changing the el34's will do anything. BTW is this noise recently developed?

Hi Nkj,

It's difficult to say whether the noise developed recently, but I didn't notice it until I moved the system in my room, about 4-5 months ago.

Subjectively, though, it seems to be getting louder.

Best
Patrick
