Fozgometer V2


I've been interested in a fozgometer for some time now. I'd like one to help me understand crosstalk and channel separation, so I've been aiming to pick one up. Stopped by a dealer today, was told they're essentially "for people who want to waste money" and "why would you need one of those when you can put on a modern pop mono record" to measure Azimuth. I was told this tool isn't any more more correct or exacting than your ears, but they've never used a Fozgometer (even though they have access to them. I've tried this particular dealer multiple times and just always seem to leave with a bad taste in my mouth and always ask myself why I torture myself with even visiting them.

What are some general thoughts on the Fozgometer V1 or even V2? I don't own an oscilloscope nor do a have local hifi enthusiasts to help educate me. My current setup for cartridge alignment is the mirrored version that's available for $15. I'm looking to get more precision out of my alignment and figured the Fozgometer was a tool to not only measure, but to corroborate what I'm hearing. Any advice?

j-wall, No, I have never used a Fozgometer.  But I have formed some impressions by reading the several discussions of it here.  For one thing, it seems odd to me that many report it does not work correctly unless you have "fresh" batteries.  The typical 9V battery is fairly robust and maintains a minimum of 9V for a long time, given a reasonable current draw.  Fresh ones right out of the container typically measure 9.2V to 9.4V in fact. So, why does the Foz go off with even slightly used batteries?  Maybe it draws too much current.  Second, based on the instructions for its use, I gather it works to equalize crosstalk, so that L leakage into R and R leakage into L values are equal, in other words.  There is nothing per se wrong with that, but in my direct experience adjusting azimuth by electrical methods (using a Signet Cartridge Analyzer and Shure test LP), you get better crosstalk numbers by seeking a setting that minimizes crosstalk on each side, without regard for whether the crosstalk db are equal to each other in both directions.  Moreover, sometimes when I have sought to equalize crosstalk, the cartridge has ended up so obviously askew with respect to the 90 degree azimuth setting that I feared damage to the suspension, cantilever, and stylus, not to mention to LPs.  Then more recently I read the articles by Korf on azimuth setting, and those convinced me that the best compromise is to set the stylus tip so it sits squarely in the groove, by visual inspection, and accept that the electronic result may or may not be perfect.  I no longer attempt to set azimuth electronically (although I own all the test gear imaginable, save for a Foz, to do it).

I use the Fox 1 (same but uses batteries rather then plugged in).... Its made a very big difference for the better.....easy to use.....great results. Don’t forget the recommended LP for it.

@lewm thank you for the insight. I might pull the trigger to test the Fozgometer and get familiar with the experience of what is correct and what is close enough. I guess it's more of an expensive experiment to learn. 

 

@stringreen what did you notice about the Fozgometer that was missing without it? I'm looking for easy and a tool to allow me to set and forget, but also learn some things about azimuth and using tools for accuracy. 

We have two separate questions, the value of setting azimuth accurately, and the value of a Foz  to attain that goal. I don’t think anyone would argue it is not a good idea to set azimuth as close as possible to correct, wherever that is. And by whatever method.
