Bifwynne....your bubble level on the head of the tonearm would give you good azimuth if and only if your stylus was manufactured properly and mounted square on the shank and square to the cartridge itself. If you have a cartridge manufactured by a trustworthy company, you could go with your method. I use a similar method..using a carpenters level holding its weight in my 2 hands and aligning the level to the tonearm head...I have a Benz LPS and trust the manufacturer.
"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
