Setting Azimuth

Actusreus....nope...making those arm adjustments are not that difficult at all. There is a weight IN the rear of the arm adjustable with a large Allen wrench to make the arm lighter unscrew the weight a bit..to make it heavier, screw the weight in a bit. From the factory, the weight is totally in, so before you start, just unscrew the weight a bit. The counterweight can be forced around the arm tube without damage. The tightening screw captures a plastic piece, so its friction controlled. With the counterweight firm, just rotate the weight while holding the arm headshell. This is not a difficult proceedure,

I agree with Lew,
Apart from the reasons given.......the room itself can often give 'unbalanced' sound to the channels?
My left speaker fires into the room with a lofty angled ceiling over whilst the right-hand speaker has a flat ceiling.
The left channel generally sounds louder with almost all my cartridges even when I sit off-centre closer to the right?
I also used to fuss about this but now I simply set my channel balance 2 dB higher on the right.
Why do you think most amplifiers have this facility?
Relax and enjoy :^)

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.

Lewm's interpretation of my comment was correct. The experiment described in the OP clearly demonstrated that azimuth has little effect on channel output. Like many useful experiments it proved that the going-in hypothesis was false. That's just as useful as a positive result.

How does one adjust channel balance?

Cartridge alignments and adjustments have little effect on channel balance. If you're actually getting significantly different output from one channel vs. the other then the flaw is probably internal to one (or more) components. Adjusting the cartridge won't change that.

You should perform a diagnostic:

1. Is the sound balanced when playing a CD or other line-level source?
- if yes, the imbalance is occurring somewhere in the phono reproduction chain.
- if no, the imbalance is occuring in your line stage or after.

2. If #1 demonstrates that the imbalance is occuring in the phono reproduction chain, try reversing the cartridge clips. Does the imbalance flip sides?
- if yes, the imbalance is internal to the cartridge. Repair or replace the cartridge.
- if no, the imbalance is internal to the tonearm wiring or phono stage.

3. If #2 demonstrates that the imbalance is internal to the tonearm wiring or phono stage, return the cartridge clips to their normal position and reverse the phono leads at the phono stage inputs (or at the TT if you have a detachable phono cable). Does the imbalance flip sides?
- if yes, the problem is in the tonearm/phono cable. Check and clean all connections. If the imbalance continues you probably have faulty wire (seems unlikely).
- if no, the problem is in your phono stage. Check tubes if you have or try another phono stage.

The diagnostic process is tedious but critical for accurate problem solving. Isolate the cause first. Then decide what needs adjusting/repairing. Making adjustments without examining what needs adjusting is just, "Ready - Fire! - Aim." ;-)

I've eliminated the phono stage during my first test. I had the fozgometer connected to the interconnects directly off the turntable. I even switched to a completely different pair of interconnects and the results were the same. I have not done the reverse channel test yet. I'll do some more troubleshooting and report back.
