Dear Arnold, Last night I realized that the suggestion I made re tube swapping to localize the source of your channel imbalance, in my last post, was needlessly laborious. Whether your phono and linestage are tube or transistor type, all you need to do is swap L and R channel leads, between tonearm and phono and then between phono and linestage (if you have a 2-box system). If the problem resides in the cartridge, the louder signal will move from one channel to the other when you swap leads between tonearm and phono input, etc. If the imbalance is unaffected, etc.
Setting Azimuth
Details:
VPI Scoutmaster
JMW 9 standard tonearm
Soundsmith Zephyr cartridge band new
Using a Fozgometer and Hi Fi News Test LP both also brand new
I'm measuring at the interconnects off the turntable.
I cannot seem to achieve a proper azimuth that will give even channel balance. The only adjustment on this tonearm is the counterweight which is weighted a the bottom so turning it side to side should effect azimuth. Only extreme changes are affecting channel balance. I changed the interconnects in case they were causing the problem, but I get the same results. The right channel is a few decibels louder no matter what I do to the azimuth unless I make an extreme adjustment which has the tonearm cocked to one side and obviously this is not correct.
