Original Audible Illusions Modulus question

Hi all,

I recently purchased an original Audible Illusions Modulus preamp and have been trying to determine if it is phase inverting. As I'll be going to pick it up at the Post Office today and play with it all weekend it would be nice to hook up things correctly the first time. I realize I can try things both ways, but...

Also, any insights you guys might have about this preamp will be appreciated as it comes without owners manual and the manufacturer's website doesn't offer much help with this piece. I believe it was made about 1982. It has a tube mm phono stage and no outboard power supply. The power cord is didicated. Tubes, tweaks and cautions are the advice I'm looking for. Thanks in advance for your help.

I have not known any of the Modulus preamps not be phase inverting. Without a cathose follower, the will invert phase.
As for tubes, look on the Audible web sight. Art cautions you about certain NOS tubes. The Modulus is hard on tubes so you need ones that will hold up for a while. Kevin at Upscale Audio sells some Russian 6H23EB Type III's that work real well. Good balance between sound and hold up well.
If in doubt, call Art Ferris or e-mail him at af@audibleillusions.com
