Hi,Any of you guys own or have experience with this? A friend is selling one and I'd like to find out if I can use this on my table with Clearaudio Tangent tonearm and Sigma cartridge.

For enlightening me about this device.
That's interesting. Are you sure it's an azimuth checker and not an antiskating checker.
Hi John:I believe that you are right. The photo looks like an Orsonic SG-1, which is a cute contraption that you mount in place of a normal cartridge and play an LP. The needle meter on the front will show you the skating forces at any place on the record. Because the stylus profile affects the drag imparted to the cartridge and therefore the skating forces, the SG-1 came in three flavors - the SG-1R (with a round or spherical stylus), SG-1E (elliptical), and SG-1L (line-contact); the idea being that the purchaser would match the SG-1 version to whatever stylus profile his primary cartridge sported.
Orsonic introduced the SG-1 around 1978 (give or take a year or so), and it therefore predated the development of the more advanced line contact profiles like the Namiki Microridge, Ogura PA or Gyger-S - which in my experience and opinion are the three highest-resolution _standard_ stylus designs available. The SG-1 will therefore give somewhat conservative skating-force readings when used with these shapes and similarly advanced custom stylus profiles (like what I use).
how unusual...Is this mounted on the tonearm in place of your regular cartridge and then the meter read to tell if the azimuth is off? In effect a clever level to gauge the azimuth of the tonearm mounting plate? I'm guessing this assumes the stylus on the real cartridge is perfectly perpendicular to the groove.
hi, i'm sorry i have no idea. that's what he told me :( :(
