I believe the rods are one of the polepieces.

But the people have a good saying - the game is not worth the candle.
I had assumed that this was a phrase only the British used so I did some research, and realising that it is based on a phrase from the Bible I see that many countries will have their own version.

You're right, in Russia they often say "...Овчинка выделки не стоит..." This means that the skin of a sheep is so bad that it is a waste of time to process it. I intentionally protected the Russian transcription, because the translator does not give the correct translation. But I am convinced that time will pass and Dmitry will find a way to solve such a difficult task.

Hello, Delta 667!
What are these rods inside the coils? The Japanese website says that the (Double ring coil without core)...
and the yellow rubber is a (Temperature protection damper from Technics)?
Hi Ivan,
Bill is absolutely right, this is a fixed part of the cartridge’s magnetic circuit. Two rods represent the north pole.
The south pole is made in the form of two metallic shiny plates. The maximum magnetic field strength was achieved in the arcuate gaps between the rod and plasitina. Part of the coil is located in this gap. When it moves along the lines of magnetic induction, an electric current is induced in the coil.
With the transverse motion of the coils, the flux density does not change and electricity is not induced.
The more accurately the magnetic circuit is assembled and the coils are positioned, the higher the channel separation at the cartridge.

The wonderful A&R Cambridge P77 that came with my 2nd hand Rega ... + a spare one too! and an unused E77 was also thrown in. I think the 1 cart itself is now worth more than what I paid for the whole lot because I had both P77s re-tipped with a Paratrace Low Mass diamond. 8)

Perhaps this design allows it to sound very accurate?
It seems to me that if this cartridge is made for today by AT, it would cost more than $5000

I have never heard one But I believe the 300 series were very good at the time. But this was the era when, at least in UK it was popular to consider certain japanese stuff to be sub par, so Koetsu was good, Technics/panasonic bad. In my teens I was silly and believed this.

Things marketing can make us believe sometimes... I have a NOS EPC-300 MC and can confirm is a mighty top performer...

Respectfully Ozzi I completely disagree with you. I have a number of cartridges that are now better than factory settings post restoration. I have combinations the factory never made and I am very happy with them. You may have a different view and that's fine, but please don't try and force your opinions on us.
Still I take his point, there is a difference between "repair" and "modification". If the result is better (or different) than the original, that would more correctly be called modification, not repair. I have no objection to hot-rodding, and if the change produces a working cartridge from a non-working one, all the better.

Very few OEMs actually repair. Mostly its a trade in, sometimes they replace all the internals so all that remains is the case from the original, but other than Ortofon with some SPUs and Koetsu I'm struggling to think of who repairs. I am sure there are more, but it's exception rather than rule. So faced with a 50 year old cartridge that the factory won't touch what would you suggest?
