I printed out the manual for the Fozgometer (thanks Nsgarch) after a bit of figuring to keep the pages in proper sequence -- first page blank on back side, then remaining pages back to back for 2/3 and 4/5.
It all seems pretty simple but I have a question about the inclusion to measure channel balance -- what is the value of that? Once you've gone through the procedure to set azimuth you're not going to change anything to adjust balance.
I can see where this would tell you if your aggregate balance of cartridge and phono stage was correct or not, but you can do that with a multi-meter. So, is there another purpose I'm not thinking of?
