Azimuth 2020

... it would seem to me cleeds that you might own certain people and apology. I don’t condone hot headed behavior ...

I’m not sure I understand you. Are you suggesting that I apologize to the two users who the moderators independently decided were in repeated violation of the group’s rules and - despite warnings from the moderators - not only continued their violations, but escalated them to the point of threatening my family and me? I’ve been around this forum long enough to know that being temporarily banned from the group is the only way some people understand that the rules apply equally to them as they do everyone else.

... it does seem to me that you have a hard time admitting you are wrong.

When I stated that azimuth is a completely different angle than VTA and that adjusting one doesn’t alter the other, I should have added "in a properly designed, manufactured and installed pickup arm." I’ll be more careful with that next time. Thank you!

I think it would be sporting if you had those people re instituted.

You’re apparently new to this forum so I’ll explain this for you: It’s not for me (or you) to "re-institute" the two violators. Only the moderators can do that. If you feel they were treated unfairly, you might want to contact the moderators and plead your case. Perhaps they’ll share with you the actual content of some of the deleted posts. That way you’ll know what you’re talking about.

Of course - given that @looscannon just joined this forum in the past week - it’s possible that he is actually a sockpuppet for one of the two banned users. No matter. I’m giving him the benefit of the doubt, as a courtesy.

No, you are still incorrect if you are talking about a pivoted arm with an offset.

... you are still incorrect if you are talking about a pivoted arm with an offset.

If the pickup arm’s pivot angle is perpendicular to the offset, changing VTA will not alter azimuth. (Disclaimer: that applies only if the arm is properly constructed and installed. If its manufacture or install deviates from "true," then all bets are off.) Why don’t you try it and see for yourself? It’s silly to argue about something that can actually be measured.

You might want to try and find a Wallytractor azimuth tool. You would likely find it quite revealing!! Malewicz understood these things.

This is all pretty basic geometry, folks.

First of all cleeds I am not a him, I am a her. 

It seems there might be a problem with definitions here. 
With any offset arm changing the VTA will ever so slightly change the azimuth. Within a reasonable setting for VTA the change is trivial but it is proper to set VTA before setting the azimuth.  cleeds, you said something about a tonearm being "true." What did you mean by that.

While I am at it I have not properly introduced myself. I am a retired psychologist. My father was an old time TV repair man. He also was an autherized Zenith dealer and repair center. For special customers he would make house calls. I frequently went with him with his big black case full of tubes and parts, the things that frequently broke. It was not long before people had him repairing their Music systems also. A lot of it was Zenith back then, big cabinets full of speakers with the changers mounted under a lid at the top. So I guess this is how I caught the bug.

I was an only child and I think my father really wanted a boy. I willingly took the role, a bit too seriously. By the time I was 13 I had already broken 4 bones, my left clavicle, both wrists and my sternum. Dad called me his loose canon. 

By age 10 with dad's help I was building Eico and Heathkit radios and record players. My first record was Meet the Beatles. Dad liked Jazz. 
It is a continuum from there. I do not have a favorite format. I listen to everything. I love glowing tubes and big hot class A amps. Anything that plays a record is fine by me. We have to keep them pressing records.
Buying FLAC files on line is the new thing and I am contemplating exactly how I'm going to set it up but that is a topic for another thread. 

Greetings and Salutations All,

"If the pickup arm’s pivot angle is perpendicular to the offset"

What is a pivot angle and how can an angle be perpendicular to anything?  I fear you are in over your head.  Just as well that this matter be dropped.
