Azimuth question

I have noticed that some arms need to have the ground wire connected to get an accurate reading, others don't. Perhaps the guy with the 15 degree error had his ground disconnected.

The better way to go is the Feikert Adjust program. I have used the Fozgometer and I now own the Feikert. Besides being much more reliable it is much more accurate. Add to that it can be used to check speed and frequency response, for just a few dollars more.

This of course, just my opinion.

Lewm, whenever someone recommends the Fozgometer...
You seem to have a bucket of ice water at the ready. Keep up the good work, helping to protect gullible (or incompetent) audiophiles from getting ripped off. :-)

I hate to deflect your cold water, but if the Fozgometer was that bad I would expect to see a bunch of them for sale at discount prices. But you seldom find used Foz's for sale on eBay or Amazon or the many forum buy/sell websites. (I suspect that as the vinyl bubble subsides we'll be seeing more of them. But I also expect to see a bunch of turntables, cartridges, phono stages, RCMs, setup tools, and records for sale as well.)

That aside, Mr. Fremer said he got the same results with the Fozgometer as with the digital oscilloscope. That's good. No?

Enough people buy Fozgometer for ease of use.

Many voltmeter with notch filter can serve the same purpose.

I use a Phonic PAA3 meter which has many more functions for not mch more money.

Tketcham, I too noticed that I might appear to be conducting some sort of vendetta against the Foz. Believe me, that is not the case. I have been moved to comment several times, it's true, mostly in response to the comments of some who actually own the thing. It's often difficult to tell whether the user does not understand how to use the Foz or whether the fault(s) lie in the device itself. I tend to think it's more the former than the latter, but that implies that the Foz needs a better more explicit instruction manual, at least. This latest business about precise battery voltage also stirred me up, I must admit. I will maintain radio silence from here on, I promise. I actually have high regard for the Fosgate company and Fosgate the person.
