Old Dual gimbal arms? Hey, I had a 1218 and a 1229 also. We must be long lost brothers!
Warjarret,
Most of us do adjust azimuth (I hope). As SirSpeedy said, since there's only one ideal setting for any given cartridge it's pretty much set and forget.
Test tones and measuring equipment are effective for azimuth and I'm part owner of one such device. The better my system gets, however, the less I need it. I can adjust azimuth by ear just as accurately - and alot quicker.
I haven't bothered with our Wally Analog Shop (or even Dan_Ed's lamps and magnifiers) in over a year. When our system was less resolving the Wally did the job best, but since we couldn't hear much difference it barely mattered! The money it cost me would have been better spent on system improvements, or more LP's. Wanna buy my share? :-)
