C2200 Phono Section

I am using the phono input switched to AUX with my Lehmann phono preamp plugged into it. I see that the tubes are still glowing? The manual states that the tubes should not be active if the input is labeled AUX. Can someone clarify this for me? Thanks!

There are 8 tubes in a C2200, The front 4 for line stage, and the back four turn on ( you will hear a click) when you select phono. You may be seeing the front 4.

I would venture to say that you are correct. I will check to verify. Thanks for your response. I am chasing a ground hum from my turntable and during my investigation I just happened to notice the tubes. Thanks again!
