Fidelity Research FR7F history/changes

@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). 

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.

But this topic is ABOUT FR-7 cartridge.

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.
