Jamnperry, there is the Analogue Productions test record, this even may be better as the 1kz tracks are longer.
Kotemaori, I would think they have you measure at the speaker outs in order to get the readings closest to what they would be coming out of your speakers. Therefore, taking into account the IC's between phono pre and preamp and preamp to amp, preamp, amp. It would be interesting to test at both output of the table and amp outputs and see what differences there are.
I also mis-wrote the acceptable tolerance in one of my posts as 5-10%, wrong, the acceptable tolerance is 1-5%.
I've also thought about a possible means to test electronically without the wally conversion table. You may be able to get azimuth to proper specs just by reading small reading (the actual crosstalk) in each channel.
Procedure: Play a 1kz stereo test tone and set volume to output 3ac volts (DMM at 2acVolt setting, it will read as .300 or close) at amp outs, test both channels, adjust and balance volume accordingly. Now play the left channel only and right channel only 1kz tracks. When playing the left channel tracks insert the DMM probes into the right amp speaker posts (in phase), write down the reading, you should get something between .010 and .023 or so (DMM at 2vAC scale). Play right channel, place probes in left channel, write down reading. If you have a reading that deviates more than .002 between the two you can be sure to be out of tolerance. The best I was able to achieve was a difference of .001. To reiterate: You want a differential reading of .000 to .002, no other reading will be within tolerance.
I cannot guarantee this method is best, but my own readings on big and small voltages show this should work.
