fabulous Technics EPC-100 series re-tip


I'm pretty sure many of you guys own fabulous Technics MM EPC-100 (MM) in your rasenal, especially their top models like (P or C versions) MK3 and MK4.

The question is how to upgrade this cartridges with a new tip, cantilever, suspension:

-How can do the job properly and how much is it, how is the sound after upgrade compared to the original?

-How good is the motor of this cartridge?

-It's worth to invest more in new boron cantilever, new tip etc?

-No one can provide pressure fitted tip to the boron cantilever?

P.S. I know Axel can do the job, not sure if he can change the suspension, Soundsmith will not do that. VdH is not available in my area. Who else can treat that Technics MM right ?

Anyone on here did the same to their Technics EPC-100 mk3 or mk4 ?

Trust is not sufficient reason for believe. Knowledge is much more,

uh, trustworthy. Those who know about the construction of tension

wire in the stylus holder also (?) know that exchanging the suspension

 (aka the ''rubber ring'') is only possible when this tension

wire is removed. But the problem then will be how to get this tension

wire back in its place? The re-tip is totally different question. The

problem of this Technics series is the suspension which can't be

fixed. Except, of course, for those who don't believe that low riders

exist . For them then there is no problem at all. They are able to use

the not recommended VTF of 0,25-0,5 g. 

Dear chackster, ''re-tiped and recantilevered'' is different animal

than fixed suspension. My experiece is similar but less drastic than

jpjones experience. Neither Axel nor Andy were able to fix my

two 205 C, mk 3 styli.  However I was not charged by Axel but

well by Andy. As a curious person I disassembled one of them

to see the inside construction of the whole thing. Behind the

cantilever there is a small round magnet on which both the

 cantilever and the tension wire are fastened. Tension wire is

 then centered with one screw and tighten with one other. At

the end of the tube the wire end is glued to the tube end.

Behind the mentioned magnet a small rubber ring is positioned

 for the suspension. This rubber ring can  only be removed and

changed by removing the cantilever with the tension wire at the

 front side of the stylus holder. There is no way one can put this together in the reverse. My conslusion was: never mess with 

those Technics  again. Despite the lyrical comment of the Mexican.


Dear chaksster, ''You didn't tell us from the start about your bad

experience in details''. I assume that your intention was to address

me without mentioning my name? Well there are two problems with

your statement. ''from the start'' in the MM thread is a curious reproach

while ''details'' my imply the parallel universe added to

the known one. But I wrote actually the same story earlier with

the basic statement that those Technics have suspension problems

which can't be fixed. I understand your inclination for disbelief

because that is how ''infantuation'' works. For ''my'' Silvia I was

convinced that not she but her parent were against me (grin).

BTW this is your third desperate attempt to find anyone who was

succesful with his Technics suspension repair. You are as succesful

 in your search as those who are searching for the right person

who can fix Technics suspension.  Anyway everyone who

participated in the MM thread should know that there are many

''carts of the month'' so you should be able to find some other

''darling''.

Dear chakster, seen and assuming are two different mental

processes. One can't see the suspension on the picture you

provided. But one can assume that Axel would not glue a new

cantilever/stylus combo on an defective suspension. I can see

because I know the stylus construction of the 205 seriers carts

that an small aluminum tube is glued on the rest of the original

cantilever on  the back side and the new cantilever glued

in the front side of the mentiond aluminum tube. Everyone who

owned or own any of the 205 series styli knows that by the

original there is no such aluminum tube. The new boron cantilever

is solid and can't be put as such on the (rest) of the original cantilever.

 I am not sure if this cart belongs to your friend or you but

only the former owner knows if this cart was an low rider.

My other assumption is that if Axel was/is able to fix the (defective)

suspension he would also fix my (two) 205, mk 3 styli. But he

deed not. Neither deed Andy.

Dear chackster, there are many seductions we need to fight

against in order to (financialy) survive. I think that Raul is to blame

for either the 205,MK4 or Technics 100 because he declared

those to be the best ever MM carts. Because either was impossible

to get I bought the 205,mk3 in need of ''re-tip'' which I knew how

to fix because Axel was/is my good friend. Back then I had no

idea about suspension problems by this 205 series carts. The

curious thing is this. Despite the fact that I own +40 carts I can't

stand the waiting time for any repair. In this case I needed to

add Andy's  to Axel's waiting time. Alas we are also confronted

with suffering for our hobby. My idea was to prevent this suffering

to my co-members by warning about the suspension problem.

Dear chakster, You need to  be exact in description of what Axel

deed. As I described elsewhere the (boron) cantilever in the

original cart is glued in the round magnet on the front side and

the tension wire on the back side of the same magnet. Behind

this magnet an round rubber ring is fastened as suspension.

To put a new cantilever in this construction either this new

cantilever must be glued in the magnet or  an  aluminum tube

must be put on the rest of the original cantilever and new cantilever

(solid kind) glued in the front side of this aluminum tube. Many

MC carts have such aluminum tube in front of the so called ''joint

pipe'' on which the coils , the suspension and the tension wire are

fastened .  There is no way to change the suspension (aka the

rubber ring) without removing the whole cantilever and tension

wire from this construction. The problem is to do this in reverse.

To get the tension wire back in the stylus tube, to adjust and

tighten the (tension) wire.

BTW those SAS styli do have tension wire. The old Mori who

invented the 8 form coils (XL series Sony's) and was the first

to use the ''potting method''' inside the carts  to prevent

resonaces is the guy who  made (make) those SAS styli.

Dear chakster, I missed somehow the picture by your contribution

from 09-14-2016. This picture shows the back side of the tube

in which tension wire is centered and tightened. You assumed

that the tension wire is removed but the little  ''tail'' at the end of

the tube IS the end of the tension wire. With this end or ''tail'' the

wire is tightened and after that glued to the tube end. What both

Axel and Andy try to do is further tightening of the ''tail''.

However tension wire is not the suspension we are talking about.

That is the rubber ring as by each other cart. I already explained

that removing and exchanging this rubber ring is not possible

without removal of the tesnison wire , magnet and cantilever.

But the real problem is to put all those parts back in the tube as

well tightend the tension wire thereafter.
