I have a rare FR-7f in a silver body with 2 digits serial number, I sold my previous black FR-7f after I bought more expensive FR-7fz. I do not re-tip vintage cartridges, I prefer NOS samples. I must admit that FR-7f and FR-7Fz are amazing LOMC cartridges, especially for FR-66fx and FR-64s tonearms. Now I have two FR-7fz and one FR-7f (silver). You can check some in my system. You will find all information about these cartridges on audiogon. |
I agree with chakster except with his ''prejudice'' against re-tips. This FR 7 series is from 80is. As everybody should know worn out styli are devastating for the records. Besides one can get ''modern stylus'' in comparison with the ''old kinds''. Certainly so by ''Expert stylus'' in UK. |
Additionally NOS may well suffer from suspension issues rendering an otherwise unused stylus caput.
Note the "may" dependant on materials of construction and Environmental conditions. |
@totem395 you never owned FR-7 series, because you don’t even know about SEALED SUSPENSION, clever design from Ikeda-San. This cartridge NEVER suffer from suspension problem! Never ever!
NOS sample of the FR-7f (or fz) is a Holy Grail! :) |
Nowhere did I mention the FR-7 cart as having suspension problems, but as often as you mention all your NOS cartridges available its prudent to note the relevant pitfalls.

I know this is a hot and controversial topic, but I have never owned a vintage phono cartridge that actually had insoluble problems due to aging of the suspension. In my experience, a few spins on the break-in bands of the Cardas test LP have always worked to bring a long dormant cartridge back to life. What we can never know is whether it then sounds the same as it did at birth. For sure, there may be changes due purely to aging, but the nature of such changes is lost to the listener. The cartridge can only sound good, great, mediocre, bad, etc, with the attendant faults and virtues. I take them at their "here and now" value. I guess you could conclude that bad sounding vintage cartridges may have got that way due to age, but it’s only an educated guess. I can only think of one or two out of dozens that fall into that category, and those one or two were "pre-owned", which means they could have been abused by a previous owner.

I have never owned a vintage phono cartridge that actually had insoluble problems due to aging of the suspension Cant dispute that statement - perhaps you could try cleaning your cartridges in an ultrasonic bath. |
@totem395 You have to understand that in Russia nothing ages. When @chakster looks in the mirror each morning he sees a young 17 year old man, hasn’t aged a bit in 50 years.
Of course on the several occasions when Dynavector rebuilt my vintage Karat Nova 13D for me they replaced everything - generator, suspension, cantilever and stylus. but then what do they know - they have only been producing cartridges for 50 years.
And when you send your precious stone bodied Koetsu back to Koetsu for new tip, yes they replace everything, like Dynavector, but then again what would they know, only been making cartridges for 50 years like Dynavector.
And of course, if you are in the business of peddling NOS vintage audio gear through audio forums to Billy Muggins then it goes without saying, all NOS audio equipment remains perfect forever - caps dont dry out, no corrosion, rubber lasts forever, micro seiko copper mats never warp, ..
I’m thinking of putting an old Grado GT into a time capsule so in 1500 years, long after we’ve gone, the next species will be able to enjoy Song of the Volga Boatman and my favourite Postman Pat album on a vintage Linn and marvel at what might otherwise have been lost.

Hey Dover, I realize that you live to skewer, but the Oxford English Dictionary gives 2 definitions for “insoluble”, one of which is a synonym for unsolvable or incapable of being solved. If you want to argue on the subject at hand, go for it. Otherwise bugger off. |
Our former member dertonarm ( Der Tonarm) or Dietrich Brakemeir owner and designer by Acoustical Systems was long term admirer of FR-7 fz cartridge . He retipped his sample 4 times in Japan. I think he uses at present his own cartridges. But he is also interested in Ikedas cantileverless kinds so he got my REX to investigate. I assume he will try something in this ''direction''. But my intention in this post is to ''refute'' chakster ''prejudice'' against retips (grin).

@chakster looks in the mirror each morning he sees a young 17 year old man, hasn’t aged a bit in 50 years. I’m 45 soon, not 67 Some of my NOS cartridges are a bit younger than me, but we are good. Some of my tubes are much older than me and they are still better than new tubes. |
You have to understand that in Russia nothing ages. When @chakster looks in the mirror each morning he sees a young 17 year old man, hasn’t aged a bit in 50 years. LoL :D |
I believe the "magic" cartridge I have was 1 of 2 supplied to the previous owner... |
Above statement should have included ".. by Der Tonarm." |
trytone, ''German sense for humour'' is not an compliment. |
But this topic is ABOUT FR-7 cartridge. Of which cart suspension is as pertinent as your NOS stock. |
