Phantom Supreme to 4Point-14?

@nandric : You are wrong again and talk because you have " mouth ". I never posted if the EPA 100 is better but only about its overall design made not by a single person but for a company that in those times belongs to the japanese gigantic Matushita group where Panasonic belongs too.

You can be sure that no one has more resources, dedicated and experts engineers, quality level of design and excecution of designs that TECHNICS.

In those times Technics never did a single design mistake in all its analog audio items. Technics manufactured TT motors for companies as Micro Seiki and others, his SP-02 was designed expressily to use as a motor for the recording cutting machines and even the SP10 MK3 motors were used in those cutting machines. You have no idea what you are talking about. With all respect to Ikeda and Reed you named they are almost " nothing " against what was Technics in those times: a " brutal " corporation.

 

There is no single problem with heavier counterweigths in the EPA 100, Technics gaves it as an add-on for those customers that need it. The tonearm bearing desing is unique gimbal kind using 20 precision ruby balls ( Technics precission not other manufacturer level. ). Got it? period.

Dea Raul,

I have no intetion to contiue the disput with you about EPA 100. My feedback

by oweners mentioned those ruby bearings as  problematic because those

''give up'' as first. Like dampers by EMT cartridges. I am wondering that

nobody in this forum has something to say about this issue. I sold both

of my EPA 100 for the given reason of ''not suitable for MC cartridge''.

Try to balance with its counterweight an Ikeda FR-7 of any kind or

those ''big Ortofon's''.

Dear Lew,

I assume that everyone is familiar with your ''deviant love affairs'' in the

sense of prefering TT's about all other , say, components. Your tonearm

preferences are directly related to your TT's. I ever try to get your 

Kenwood without meantioning my reason. Ex post I can expalain.

I own this ''better Breuer'' with 6 ( aka six) counterweights which is

AS MADE for your Kenwood. For the second arm that is. I never

mentined this reason to you because of the fear that you would ask

ME to sell the ''precious'' to you. How could I refuse such appeal

from my English teacher ? The ''deviant'' preferece is easy to explain:

by your resolute  refusal to sell to me your Kenwood. 

When it comes to Vintage TT's and Imports from Japan for the present purchasing environment, Do Note:

As a result of my very recent experience of purchasing my beloved Vintage Japanese TT Models direct from Japan, of which one has a Stainless Steel Machined Platter and one has a Heavy Plinth (Added Weight).

The latter half of 2023 is presenting ludicrous shipping costs to the UK, I suspect these will be reflected in most long haul flights.

Combine these incurred shipping costs with the 'to be' added 25% Import Duties and it is not long before the cost of the Bargain find, will become appreciated in cost by close to 150%-%175 Uplift to the purchase cost.

Then there is the Gamble on the condition of said purchase, I expect an individual to have to add another £60-80, without any shipping costs for the Platter Spindle  Bearing Investigation/Service, this should be considered a mandatory work to be undertaken. Start adding exchange parts due to deterioration or misuse, and the cost can easily increase by £50ish. 

For the full Overhaul/Modernisation of the Platter Spindle Bearing, to the level of performance I see as being extremely attractive as an addition, especially using modern Materials, Extremely Tight Machining Tolerances and Lubricant selected to optimise the overall function of the parts, I expect to be paying out £150-£200 for this, if no complications are met, and this is without any shipping costs included.

I would not know how to predict what a complication might need in monies parted with to correct the issue discovered. I am aware that Fatigue Fractures in a Spindles Bearing Housing has been discovered as a really unwanted condition, and abraded Spindles as well as scoured interference fit Balls at a Spindle Base are commonly encountered.

The above are reasonably easy to deal with, but will be more costly, in either version for the correct skill set to carry out the tasks. Obviously the Cracks in a Bearing Housing present a completely different challenge.

The 'Fly in the Ointment' and most difficult to detect is the Electronics being with a fault, Investigation into this, where the working circuitry is optimised for the performance, is not for the novice EE, or even the EE that is adept in EE tasks.

If such an EE as above does want to try there luck, I'm not to stand in their way by being discouraging.  

For my own peace of mind, and for my owned models, the Electronics are best left to the time served EE, who has a history of being hands on and proven record of really knowing what is what.

It to me seems that if a Import TT of any Vintage, or a Vintage TT is purchased without a well known history, the idea of assuming it is fit for the purpose of being a ancillary in the Vinyl Replay Trilogy, that can have the other two supporting ancillaries come with a combined value of £3k - £10K, is a very high risk assumption. It is something I would certainly not be carrying out or encouraging.

All 'go to' TT's from a Vintage era, used by myself, are only put into regular service   after having being dealt with, either Mechanically or Mechanically/Electronically,  by a renowned specialist who's works come heavily recommended.

I would predict for a Vintage DD TT, a basic investigation and odd swap of component to be of a Cost of £180ish, a Model with many faults needing discovery and correction can easily sweep upwards towards £500, and again no shipping is added to these costs.

For the novice, trying to work out what they have bought into.

If the TT switches on and rotates, placing an ear to the chassis/Platter area will/will not produce a audible noise from the mechanical function of the TT.

 A Stethoscope placed on the Chassis/Plinth will be a very valuable device to pick up audible sound, but to the novice user, the sound produced might cause alarm to them, even if a only minor case.  

If Mechanical Sound is detected by the ear, the Chassis or Plinth can be gently touched to feel if vibration can be detected.

If a Speed Rotation is wanting to be checked, it is best not to rely on any inbuilt speed control devices. It is best to use a off board independently powered Strobe  device.

By using a Standalone Strobe device Speed Fluctuation will be seen with immediacy.

What will not be known with immediacy is whether the fluctuation, is resulting from the Electronics for the Mechanical Interface in the Spindle, i.e, a very worn Spindle Bushing can create a eccentric rotation, which will manifest on the Standalone Strobe as a fluctuation.

I am wed to Vintage TT's for nearly 30 Years, starting with Idler Drive and continuing with Idler Drives for quite a period of time, and in the past 10 Years moving over to Imported Vintage Model DD TT's from Japan.

I will not discourage anybody from the experiences that can be created, the more the merrier who shout from the Roof Tops their newly found satisfaction.

From my end, it is best for those that are new to the idea, are the ones receiving guidance to become individuals that have something to attach a Caveat Emptor approach to.

Knowledge is Power, or in case of Vintage TT's, it can be a case of keeping the hard earned in the Bank. .    

Dear pindac, If your warrning is directed at me in connection with Lew''s

Kenwood you are at  wrong address. I bought only one cart in Japan,

Ikeda's Rex because I was not able to find one ''in de West''. But my

eaxperience with Japanese intermediers ( plural) was the reason to

never do this again. But Lew is differen because one of his sons

live there. So he can search for ''real bargains''. I buy only from

persons whom I know.

But your warriing is important  for the novice in our forum.

BTW I never ''grasped'' Japanese ''export success'' . Some ''things''

are simply incomprehensible, Like, for example,, American collectables.
