Yes, please call me at 651-330-9871 if you have questions or issues with AVA equipment.
I don't check for PMs here often so they may go unnoticed.
Yes, I can supply anyone with user manuals for most older AVA equipment, but I will need your email address to do so.
Regarding the old tube phono section in that T7SL preamp, the best way to add MC capability is our Vision Q free standing phono preamp which will plug into any 9unused set of line level inputs.
