One brit did try to make a medium to high mass turntable in the 80s. I know a 1pk high hand has one in his den.  
 
The platter is made from solid brass and the designer put in not three springs underneath to level the turntable. Not even four. A total of five lor!  
 
The sound? Absolutely no idea!

Daiwok and Bobui,  
 
I think the inverted bearing design of PT was also an innovation in 80s. Not sure it's true or not. I shall wait for a SME mounting type Orion to save all the fuss.  
 
I have long experience living with Linn's MC from Asaka -> Karma -> Troika -> Akiva. Allow me to opin that each change was a real upgrade to me. The Akiva is a real gem and biggest improvement ever, far excel her ancestors. The addition of Akiva to LP12 completely wash out my migration plan. Now, I am watching their new Linn MC flagship, Kandid. Looks very very promising to me la.  
 
Hi, mda,  
 
How's the EMT turntable? The German troop is also a good contender to Brits, or even better? Linn is launching their new Linn MC flagship, Kandid. Itchy?  
 
Ah Chi,  
 
Will call you for a spin when the new bearing jewel returned from UK. Everything comes with the PTA looks fine.

The TT markets started shrinking quickly from the early/mid 80’s due to the introduction of CD.  
 
With the Japanese giants started pulling out from the TT (especially DD) market, very few, if any, audio firm could survive developing DD TTs, which demand heavy R&D. In contract, you can develop BD TTs cheaply by comparison.  
 
Also, started with the Linn, audiophile was led (and I think being misled) by the media to believe BD was superior to DD or ID. I suppose we know better now!

Ceramic ball bearing are also good, there is friction coefficient attached to these bearings telling you how smooth they are - I forgot what the unit of measurement is. Nevertheless, these are super smooth BUT supper hard ! and can eat into your spindle over time ! bewarn [email protected]@ - yes they also sound good !

I was able to contact a UK firm, called True-point, who is happy to carry out the bearing replacement for my PT Anni at a very reasonable cost. They are precision enginneering firm and a major supply to PT in the past under the old name Melling. They bought out all original sapphire bearing jewels from Pink Triangle when PT ceased business in 2002 or 2003. If you asked funk firm, they sold you the jewels at 3 times the price.  
-----------------------------------------------------------------------------------------------------------------  
 
This reminds me of my tests on the ball bearing for the Lenco. The Lenco spindle sits on a ball bearing, this is made from harden steel. I actually replaced this with a sapphire bearing and it sounded terrible. Ruby Sapphire bearings are not expensive and can be bought direct from suppliers in Switzerland. I am not saying those used on other bearings sounded terrible, just it did not work with my Lenco bearing.  
 
As for bearings, bearing oils change the sound and should be mated with the motor - yes with the motor, as its is not a matter of how many revolutions you can spin freely but the oil is a damping against motor cogging regardless if it is AC or DC.

I also had the Rega Planar - best bang per buck until I got my Lenco for GBP30 !  
 
The Townsend Rock - was an R&D project from Cranfield University in Cambridge. The plinth was partly made from Plaster of Paris and the resonance measured was amazing, but does it means it sounded good ?  
 
Roskan - I heard this TT, too linear sounding for me .... bordering boring  
 
Linn LP12 copied the AR XA  
 
Early Linn cartridges sounded best because they were OEM from Supex, the later ones were OEM from Lyra.  
 
The original VPI turntable was a copy from its own French OEM supplier !  
 
Clearaudio lower end cartridges are Audio Technica AT95E with wooden bodies !!  
 
So who is copying who ? @@

In UK, there are so many legendary turntable designs arising in 80s.  
 
The three champs in UK's high-end market were, LP12, Pink Triangle and Logic DM101, all orignated from different design and engineering thoughts.  
 
From my memory, there are some other good names worth mentioning:  
 
1) Elite Townshend Rock, remember the innovative oil damping tonearm trough design? It was ranked just behind the big 3. Eventually, I bought a healthy one for my collection lately. I'll order the silicon oil and spin it later on.  
2) Mid priced Logic (not DM101), Systemdek and Heybrook. I couldn't afford the big 3, so settled with a much cheaper Logic model with a Helius Scorpio on it.  
3) Dual - entry turntable for the beginner  
4) Rega planar 3 - how can we miss this legend. The RB300 tonearm brought real life and huice to the turntable. Feikeung told me he bought a Rega in Canada.  
 
Roksan had not yet arrived until mid 80s.  
 
Bobiu, the DM101 is rare in used market today. I never had a chance to touch it. A year ago, I saw a crap one in UK eBay in absolutely scrapy condition selling a spare part. Shame on the owner.

>Extra Pulleys on belt drives is a good idea to maintain the tension on the belt and also reduce resonance. This idea is also implemented on the Shroeder Artemis TT and its taken from Reel to Reel machines. <  
_________________________________________  
 
The extra pulley implemented on the Artemis TT also helps to increase the contact area, therefore friction, between the belt (I believe it is actually some sort of mylar tape) and the motor pulley to minimize belt slippage!

A ruby on the tip of a bearing shaft. Aerospace grade honey comb sub chassis and a servo controlled regulated power supply for the DC motor. And you get all that in the early 80s. Over enginerred even at time when the audio industry was only just begun.  
 
Is it still worth keep one in 21st century?  
Yes ar! But first you must understand why the Brits perfer low to medium mass turntable.  
 
Second, the Brits were very much focus on isolating the three sources of vibrations using the lightest materials. PT is a good example effectively balancing design and enginering to acheive what they beleive is most essential in a turntable design. Isloation lor!  
 
What I see in many 21st century turntable is over emphasis on finishing using modern equipment and tech. In terms of sound/material enginerring and design, emmmmmm...........  
 
To me, the Linn inital design did have three special elements. One is the die cast outer platter. Second is the moulded lid and last but not least is the Asaka cartridge.

Picture shows The Funk Firms' attempt to improve/upgrade the Pink Triangle's lower models with extra pulleys but this can also be implemented on the Anni as well.

The Pink is well engineered and well made - just did not like the sensitive springs. In all honesty, the Alphason and Voyd and the Pink were all better than the Linn. The Pink was modern day thinking in the use of materials, more modern than the Voyd. The Voyd was forward thinking in terms of being the first turntable to employ 3 motors - way before Clearaduio and it has a split phase power supply. The Alphason was the daddy of them all - first with 2 motors, first with heavy record clamp, first with MU shielding - that's right bobui - the metal under the platter is to shield against the motors. The Alphason was so over engineered at the time, it died !  
 
Now for those who want to speak out for open mindedness, the "Pink" name was not by accident - it is a statement from the owner !

I have been through the following in sequence:  
 
Linn LP12  
Gyrodeck  
Pink Triangle PT Export  
Orbe  
Alphason Sonata (x3)  
Voyd - The Voyd  
Linn LP12 (again)  
 
the only thing remaining is the Alphason due to its superior engineering. The Voyd was my reference for a while until the Lenco arrived ..... the difference ? its like a Golf GTI 16V (peak of 80's hot hatch) vs current Skyline GTR

Oh yes, the Voyd. One of the two missing in my Low to medium mass classics turntables from the 80s to 90s. The other one I am longing for is the Logic DM101.  
 
I know someone who used to have a Voyd here but sold it before I even had a chance to meet him. Hope he sold it to gain space for a Lenco lor!

Dennis, if you are interested in a Helius Orion, there is one that has been in shop window for a long time in HK. Let me know and I can direct you.  
 
Of course, I can assist you in cutting out an arm board for the Orion. I have one myself on a PT original.

Thanks to Chi, Daiwok and bobui,  
 
Mine carries serial number 305 @ 1992, non battery power supply. Seller was first owner since 1994. It came with a Michel RB300 and a Goldring 1042 MM.  
 
It's rare to find the battery power supply today. There is one offer found in UK but seller don't ship.  
 
MY PTA looks great in condition. Still plenty of juice left in the suspension sping. Just a damage glass plate and bearing needs replacement. I gave it a spin to quick test the power supply, very promising. May settle for an Audiomods arm first.

Well done tracking down where to buy new PT parts and I don't suppose Arthur Khoubesserian told you this :-)  
Don't forget a new belt as well.  
Daiwok has a point on the battery power supply but never saw one for sale separately.

Dennis,  
 
Congrats ! you may want to talk to Scallywag on his experience. Now for power supply - you need to hunt down the Battery version !!  
 
I had the PT with SME V in my system before, the only complaint I have is the springs are so sensitive to temperature change ! @@

what arm you aim to mate with the PT?  
 
PT was one of the very first turntable in those days/80s uitlise a DC motor. When Linn was using thin metal sheet for the subchassis in its initial design, PT consturcted its subchassis from aero grade aluminum honeycomb board which can only be found in an aircraft.

Hi, dear brother, si-hing and sifu  
 
In your opinion, which tonearm should best match with PT turntable. I missed the Helius Orion last week. How about Audiomods or SME V? or any other good suggestion?

Here I come again with the Pink Triangle Anniversary.  
 
I just bought an used Pink Triangle Anni (PT Ani) in great condition from UK.  
 
I am sending the bearing shaft to its remaining UK's precision bearing firm, who bought out all original PT bearing jewels 10 years ago, for a new bearing jewel replacement. I also ordered a new top glass plate to restore both the performance and its gorgeous PTA look back to day one condition.  
 
I'd tried their first generation PT1 manufactured in 80s a while ago, so impressive, so I'd decided to sell the PT1 and upgraging to their pinnicle star PTA. Still missed the generation 1 PT1 today, it sounded with glories and showed no sign of shame even confronting with my other modern turntable costing 10 times mores.  
 
Will post photo.
