My new Fozgometer.

Works for me !
image.jpeg Found some time to try my Azimuth meter and adjust the Denon DL160 cart I am currently using. Following the directions and using tracks 2 and 3 of the test record I got what I think is dead on for the Azimuth. Both left and right channels are now showing the same reading on the meter. After the fact I can notice a substantial Bass, Midrange and High improvement. and the separation is way better then before. Before using the meter I would set the Azimuth using the mirror method and eyeballing the stylus to what looked right, After I set the Azimuth using the meter my head shell came out cocked about 3 degrees clockwise ( see picture ). I would never have thought that the stylus tip and cantilever was that far off but the meter tells me different.Oh ya! Before I did anything I calibrated the meter using the method described in the manual. It was a little bit off calibration so I am glad that I did. Is it worth the money spent? I think so, at least for me. I have 10 turntables each with its own cart and I move them in and out of service. Currently I am using the Yamaha PX3. I think It's my favorite

Very cool. What does that device measure? I suspect it is the RMS voltage from each channel. ?

It is reading voltages from the cartridge. The scale on the meter is just increments with no real values. The object is to get both left and right channels too the same point on the scale while playing a 1k Hz tone.
 
Sometimes it's not the stylus/cantilever that are off, but the magnets and coils.
 
Interesting. I've seen these advertised and often wondered if they were "worth the investment". With my arm/table I can adjust azimuth on the fly. Using a test record with azimuth adjustment tracks it seems to be pretty easy to do by ear, but I may not be getting it spot on? I do hear the improvements you describe ((greater separation, more space in the soundstage, bigger body in the mids, clearer highs (sibilance goes away), and a more solid bass)) when the azimuth is adjusted - so maybe I'm getting close enough doing it by ear on the fly? Or, should I try one of these devices so as to tweak it even further?
 
If we end up with a cartridge that is leaning like this something is wrong. The needle should fit the groove the same on both groove walls.
 
I use the test record with the 1Khz tone that alternates between channels, connect to the PC, use a program called Goldwave that has an input monitor that I can adjust the azimuth to get the channels equal in input volume. The program has an eq meter with the numerical db input value for each band. I set it using the 1kHz band obviously.

I have been "1 click away" several times from buying the Fozgometer.

Or cartridge manufacturing and the marriage of the stylus is not done to that high a standard.

No it isn´t. But what I mean is that the needle should perfectly fit the groove. We should not try to strive for a channel balance that is not achieved when the needle is perfectly fitting the groove IMO. It´s better to live with a natural tolerance on channel balance than skewing the needle and cantilever as I see it. But the real action in this case should be returning the cartridge.

Now I gotta get one. Even if it doesn't work, be cool to tell people I got a fozgometer. <G>

Begs the question though. What do you use to calibrate you fozgometer?

There are a few threads on the net about calibrating the Fozgometer.

Evidently some meters where shipped out of calibration or were knocked out of calibration during shipping.
 
Everything I know persuades me that this Fozgometer is an excellent device. Your photo confirms it. Very few stylii are mounted perfectly square to the cantilever, most are twisted one way or the other. It is impossible to know if the stylus is centered and perpendicular to the record grooves with any visual inspection. Only by measuring the electrical output of both channels can the final mounting be optimized. We used to use a Shure test record and an oscilloscope to accomplish this and almost always had some degree of twist to the cartridge when both channels were balanced. Methinks this Fozgometer is very worthwhile.
