Usually if the soundstage is lacking it due to the azimuth being out a touch.

I was thinking of starting a separate thread asking people how they go about setting their azimuth, as just eyeballing it, even using a azimuth alignment tool to see that the cartridge is level in the horizontal doesn't always mean its correct, as the stylus itself might be set slightly askew in the cantilever.

I see there is a product called the Fozgometer that measures it electrically, but paying $650 for one doesn't really appeal to me.

I've also read that it is possible to do it using a multimeter, but also while reading about this read that there is some dangers involved doing it, which TBH I couldn't understand just what exactly they were, they seemed dire anyway.

 

 

i can only just remember the approach and science behind it, hopefully someone can fill in the gaps...

 

but it involves something like putting on a mono record,  switching over the cart wires on one channel at the headshell, putting the phono, pre, or amp to mono. Then running one speaker out of phase by swapping round the +/- connections. (but I'm not on that last part regarding speaker leads!!!???) 

 

if you've done it right you should get close to but not necessary 100% cancellation of signal from the speakers ( I'm guessing at the listening position?) but if not you have an idea of which way to adjust.

 

now reading back over my content here it sounds like whack job noodle head BS. hopefully the brains trust can work it through

I've just been doing a quick search on the subject since my last post.

It seems adjusting Azimuth opens a whole can of worms.

Basically one reason some are saying you can never get it spot on if measuring electrically, is because every cartridge has a certain amount of in-build channel imbalance.

So if you were to try to get azimuth spot on electrically, it doesn't mean your stylus is sitting properly in the groove.

I also found a DR Feickert article on the matter.

http://ttsetup.com/images/AP_Azimuth_Compendium_english.pdf

 

Watching this video below was what got me thinking how things can get out of whack if you follow one way of doing things.

I mean have a look at the severe amount of tilt that this guys cartridge has ended up being set at in his headshell,

I don't know if the results were better, or he has made things worse going down a rabbit hole, but it just doesn't look right to me.

I found these (parts 1-3) rather helpful in understanding azimuth and the implications of trying to adjust it:

Thanks for that, easy to read and far easier to understand than most of the other articles I've read, they have tended to be so technical they seem to contradict themselves.

 

It will be interesting to see what results I get setting up a Garrott P77i cartridge that has a Microscanner stylus on in.

My turntable is a new Technics SL-1200G, so the only azimuth adjustment will be with the amount of play I have with the detectable headshell.......I suppose its better than having to stuff about with spacers.

Some minor updates on the Lenco 88 since the last photo and thats a good enough excuse for an update photo I reckon!

Machined up a cap to cover the mount of the previous tonearm, got a dust cover made by the lads in Canberra at Plastic Creations, new cork/rubber composite platter matt and a small timber box for my record and stylus brush. 
 

Edit, added a second photo, cover looks great in the dark with the lamp on.
Cheers,

No doubt azlmuth is important but fixing alignment cured the inconsistencies I was getting after switching from the GR.

I set the azimuth with a mirror to get the cartridge perpendicular but then didn't experiment further. I actually have a Fozgometer somewhere - haven't used it for many years as I found the readings inconsistent. Maybe I'll dig it out and try again.

Ok,

I managed to purchase the TT I was really after of great member here!

Technics GR as I only dable on the dark side.

Then I was made redundant at work in Xmas with a Feb finishing date - so no payout, and also did not advise wife of said purchase.

Suffice to say I was in a tight spot but no way did I want to have to resell.

 

Luckily I decided to lay it low at a mates house until payout came in.

 

Just unboxed her this week and I’m ecstatic .

Here she is :

Congratulations - I loved my Technics GR which I ran for just over 2 years (now upgraded to the G) - she never missed a beat, and the Ortofon Bronze was perfect on her too - she will bring you much joy and happiness & she looks lovely insitu.

I am no photo buff, but for some reason I think it is absolutely brilliant. May be it is just knowing that there is a Lenco heavy platter at stage left. 

Excellent

Hi Guys, Here is my latest incarnation of what started out as a Lenco 78. Now is has a separate DC motor driving  the platter with a Mylay belt. The whole top plinth sit's in a bed of sand. The increase in spacial information & bass depth & slam with this arrangement is quite remarkable. Arm is a Temma Merlin 12''with 1847 internal wire (best wire I have ever used) Cartridge is a Ortofon MC25FL, re-cantilevered with Boron & Micro Line stylus. This cart would easily trade blows with any other around the $3-4 K mark

Very nice.

What material do you have on the platter?

[highcut28]

all thats left of the Lenco is the platter as i am sure u changed the bearing !!

My guess is a 20mm delrin "mat".

Hi,  Thanks for the comments, The platter is 30mm Acrylic. I did use a Lenco bearing, one than had just been refurbished by Wakefeild Lab's in the UK. 

As I said in another forum, Is a Linn still a Linn when it has an O/L DC motor & controller & Naim Aro tonearm.

whatever rocks yr boat
Its a very cool turntable 

[idiotek]

Almost 12 years since my last turntable post, sharing an update after receiving my turntable back after being serviced by STS Turntables in Tennessee. They disassembled and rebuild the whole turntable with new wiring, power switch, capacitors, suspension, idler wheel, spirit bubble, chassis mushrooms and a new coat of paint. Here's are some pictures before, during and after the rebuild:

That's a very interesting point, TA.  Back in the old days, Linn said exactly that (it's no longer a 'Linn') when OL brought out their DC motor control unit.  Then of course ... they came out with their Radikal!  

 

Given there have been so many improvements over the years ... who can really say which version of an LP12 has the "definitive LP12 sound"?

 

One thing I can report though - when someone who owned an LP12 came to listen to my 'SkeletaLinn' ... he said it was unmistakably a Linn!  So I suggest that means the essential "Linn sound" is delivered by having:

• springs
• belt drive
• AC motor
• and the Cirkus bearing.

Having just installed a Karousel, I would say it doesn't change the character of the sound - merely delivers better resolution.

Hi, yes I agree. I have the unit I posted & a standard refurbished Lenco. They bot have the same family sound, however (like most people would hope when you modify) the Lenco in the sand loaded plinth sounds WAY better.

(I suppose that is why Linn are asking $6000+ for their new DC motor & controller!!)

INot a new turntable but I have put the Alphason on the PT anniversary. It is much lighter than the PU7 and a better match for the PT.

Wonderful, this exactly setup was my second ever TT back in 1986. Such musical sound.
