"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

In contrast, I know of a guru who claims that if your optimal azimuth is more than 2 degrees off vertical, you should send your cartridge back to the maker as defective. I do not agree, but he is quite adamant that in most cases azimuth adjust is not necessary, off 90 degrees.

Doug, Perhaps this is blasphemy of another sort, but have you ever checked the actual electrically determined crosstalk after adjusting azimuth by ear?

The aforementioned guru does in fact use an SME V tonearm. Funny how that works.
