"Making Mono" for checking Azimuth

I have a Hifi News test record for checking azimuth, but it requires minimization of a signal when listened in mono. My preamp (like many others) doesn't have a mono switch. Can I just take the output from my phono preamp, run it into a Y adaptor, and feed the output of the Y adaptor into one channel on my preamp, and just listen to that channel to minimize the signal? And further, could I reduce 2:1 with a Y adaptor and then expand 1:2 with another Y adaptor, thus creating 2 channel mono?

Or - is there another way to check azimuth that I should be considering?

Thanks, Peter

Peter, is your Teres TT a unipivot? I have a VPI Classic which is a unipivot. I adjust azimuth using a tiny bubble level which is part of the stuff in my protractor kit. I also use the Sound Smith couter-intuitive device to fine tune VTF and azimuth. As far as I know, the azimuth on my unipivot is perfect.

Al, what do you think about my use of the small bubble level thingy that comes with my protractor kit? Seems to me that if the air bubble is dead center while the sylus is sitting on the record, azimuth is perfect. Am I missing something?
