David99, In a high gain tube pre-amp, tube rush is practically unavoidable. Graded tubes which have been tested for low noise levels and noise spectrum will reduce this, but rarely eliminate it. It simply isn't a solidstate circuit. In general, BE GLAD!! As long as the tube noise doesn't interfer with your ability to appreciate the music, try not to obsess over it. Just my $.02.
