Fidelity Research FR64 Black Limited Edition

Are you able to post a photo?
It is hard to imagine a black FR-64s as they are made of stainless steel and to get a black finish on stainless, it needed to be black chrome which was a fairly new process in the late 70s.
Powder coating was even later than this which is why the 64fx was black anodised aluminium I believe?

I do not believe i have a way to post a picture here.

Ok, i posted pictures in my virtual sytems thread!

Ok that makes it clearer :^)
Tha fact that it calls it an FR-64 and not an FR-64S is significant I believe.
The 'S' postfix stands for 'Steel'...as in 'Stainless Steel' and without the 'S', I think it must be made of aluminium or titanium?
We need Dertonarm to confirm what this model is.
He is Mr. FR-60 :^)

Hi Mike, this is FR-64 black edition. A limited edition from 1980.
This is a fairly low numbered edition which was introduced when the FR-64 model was discontinued in favor of the FR-64s.
In the FR-64 the lateral balance weight is a round blank, while it is a hanging cylinder with the FR-64s.
There are other small alternations coming along with the FR-64s, but this is the most notable difference between the two "brothers".
A rare one - enjoy!
And no - the "s" in FR-64s does not stand for stainless steel or steel.
It just denominates the improved version following the FR-64.
The FR-64 is stainless steel tube too, just with a different finish ( a matte satin finish unlike the shiny polished in the FR-64s).
Cheers,
D.
