Hi again

I am trying suspending symmetrex tonearm to my new Amadeus.
I have read the manual and the procedure contains 6 steps.

what is unlear to me is:

Step 1:
I assume that i have nothing to do (coarse azimuth adjustment). "Rotating the tonearm within the golf ball". Is this possible?


step 3:
"Apply a clockwise half twist to azimuth adjustment collar and install on the suspension rod"
Is this accurate? I think that has to be a little more than a half twist (3/4) otherwise collar cannot be inserted in the suspension rod.

If you haven't yet, I'd call your dealer or Mike Pranka.

First try. What do you think?

That looks pretty good to me!  Also look back on threads here on AudioCircle which discuss the setting up of azimuth.

Hi again

I read in LTD arm manual:

Suspend arm by applying one and half turns on the mono-
filament suspension around the azimuth collar apply anti-
clockwise half twist to the mono-filament suspension


I read in amadeus MKII manual:
Apply a clockwise half twist to the azimuth adjustment collar and install on the suspension rod.


I suppose that on of  the two is wrong (both arms have the same philosophy)
What do you think? Is it a typo?

On the Amadeus, the monofilament loop should have a half-twist counter-clockwise before placing it on the adjustment collar.

When the monofilament is twisted and placed on the collar correctly, the arm should have a tendency to float back to the armrest.

[watercourse]

Looking at the photo you took from above the collar, it looks like you've twisted the loop correctly. It also looks like you've only done a half-twist, so all looks well.

Hi Watercourse thanks for the feedback.

I hesitate to finalize my seting, put silicone etc because i am not confident with my setup.
I ll show another photo with exactly the  same setting but at different angle that- i think- shows something is wrong.
First photo you commended shows arm resting on arm rest.

This photo shows the arm going to the end of record. See strings getting loose and going apart each other. This should be like that  one string crossing the other?

[n1kcha]

Now i ll show another photo that seems more normal to me but in this setting i generally ignored manual and tried to achieve something that makes sense...




i am a bit confused by tha manual and dealer is more than 1000 miles apart...

I think the only explanation for this is that you've twisted the loop of monofilament the wrong way. Looking from above, can you double-check that you've turned the loop counter-clockwise? If so, the twist should get "tighter" as you move towards the spindle. It should not open up the twist.

In your second photo, there are too many twists compared to my arm.

I agree with watercourse. The last pic has too many twists. The pic earlier in the thread where rob 400 says "looks good to me" seems to be correct. However, even in this pic it's hard to determine if a counter clockwise twist was applied. The thread coming from the left side of the golf ball should pass over the thread coming from the right side of the golf ball.

[rob400]

The two photos don't seem to present the same set up. The one posted at 0313pm shows no twist at all and the one posted 0319pm shows an extra twist to what's required. As Watercourse has stated viewed from above turn the spindle anti clockwise half twist before fitting to collar spindle. Think logically we are creating an opposite resistance to the stylus's natural pull toward the end of the record. If we twisted clockwise it would be adding to it instead.

Hi
Thanks all for the feedback. I will try to implement your suggestions and see how it goes.

interesting - I have missed the whole clockwise vs counter clockwise.  My thread was clockwise. 

This fall I had a dynavector cart that was driving me crazy because it seemed to skew  the soundstage to one channel.  Even got to thinking I had a tube problem with my amp.  I replaced the dynavector (which was in good shape when checked by a tech) with a denon 103 and problem seemed to go away.  Now I wonder if having the thread going the wrong way may have contributed to my soundstaging issues with the dyna.

Based upon this discussion I have changed direction of the thread and so far no real impact that I notice.

[n1kcha]

I made the changes as you advised and here are the new pics:

pic 1 - arm on arm rest







pic 2 - arm towards the center of the record





I think are good 


Now, can you offer some guidance about "the approximately 25mm between azimuth collar and top of the arm".

From where to measure?
a) From box on the top of the arm or the arm cylinder itself?
b) To inner collar cycle or to outer cycle?

Thanks all of you for your kind advise!

The twist is now fine Nikos and the distance between collar and arm is ok. Happy listening!

Hello again.

As you may  noticed i made real progress with anti skating setting and afterwards i finished my setup!
I have to more problems.

a) No sound from one channel... I suspect the plug that connects arm cable with the plinth. It is has not a firm connection and if i touch it makes a loud hum noise. Experiments with  plugging and unplugging this thing lead to lost both channels...

b) Arm damping. Arm has a rather sharp move downwards when i place it on a record (cartridge weight is OK) . Does this mean that more silicone is needed? Any trick to check silicone level?

Update
Both channels intact. Defect interconnect was the culprit...

What is your first celebratory record going to be?
