Well Dre, the transfer function gives only correct result relative to the azimuth (= correct position of the stylus towards the grooved wall for both channels) if factor x (here: output voltage) is known and thus for each channel.
Otherwise the calculation is always a relative one (which it is here).

Dear Jtimothya, to determine the correct output for each channel you do not use a test record. You need the pure output of the coil and the best way (and most precise) to obtain that basic figure is to get it WITHOUT a groove.
It works this way: get a Nagaoka or similar oscillating stylus cleaner. This gives a 400 hz or similar impulse on the cartridge - to both channels and independent of position of stylus. This has to be measured with a precise micro-ohm-meter.
You will get perfect and stylus position independent readings for the raw output of each coil.
Simple yet effective.
If we want a figure for factor x1 (coil output) and factor x in action is a function of factor y (position of stylus polished area towards grooved wall) or factor z (relative crosstalk to other channel - which here would mean x2....) - then I would look for a way to obtain factor x1 (and x2...) without other variables depending on.
Best of all .... - it works.
Cheers,

Dertonarm,

I believe I stated that I'm not going to debate setting azimuth. I clearly stated the software does not work the way you described and your subsequent post seems to acknowledge that your previous assumption about the software functionality was incorrect.

The point of my post was for clarification only.

Dre

Joel,

I believe it is the later being frequency specific which is to our benefit. In practical application, it allows us to go beyond the loose standard of 1KHz if we choose to.

I apologize but my time online is short this morning.

Dre

Dre, I am not discussing azimuth adjustment either.
As there is nothing to discuss in a simple geometrical issue like this.
And I clearly stated that the F. software does function in a way which gives a wrong result - at least regarding azimuth "adjustment".
Period. I know it - I have it (the Freickert software...) at hand.....
So my post was purely for clarification too.

Dear Jtimothya, to determine the correct output for each channel you do not use a test record.

Maybe. The goal is merely to compensate for channel output differences prior to taking readings for the purpose of setting a decent azimuth. Whether you use a stylus cleaner or the stylus moving in a groove cut for a known frequency, the net result of what you're doing is basically the same. The cartridge doesn't know where its input comes from. If you have a point it seems to be about the specific frequency used to put the motor in motion.

From what I know the methods described in my post have yielded proven results. Thanks for your comment.
