The preamp is probably 15 years old but has had very minimum use for much of that time. The tubes were purchased last year from The Tube Store and have less than 100 hours on them.
Audible Illusions hiss
My AI Mod 3 has noticeable hiss in both channels. It does not get louder as the gain is increased and is not present when the mute button is on. It also does not matter which source is selected.
Someone said the tubes in these can make a big difference. Does anyone have any experience in this area? Thanks.
