FR64s & Orsonic Av-1s Effective mass ?

Hi Good folks!

I have an FR 64s with original headshell. Have ordered an Orsonic Av-1s/ 10 grams, to meet better compliance/ resonnance matching with higher compliance cartridges.

Any idea what the effective mass will be with this combination?

Would be funny to try for example how my London Decca Super Gold would work with this arm..😀

Hi Rauliruegas

Good point about Decca recommendations. I actually did not know that, or thought that far. Typical caveman ideology, try first, read the manual after.
Also good point to use only the counterweight for VTF. Actually I tried that some time ago, most of curiosity reasons with another cartridge with acceptable results.

I also have an Basis Superarm 9 with good damping, so its no crisis here. But I was thinking to use the classic FR arm as my second/ dual mounted arm more or less for rock music/ casual listening. Would be fun to mount something else than low compliance mc's on the FR..

I have a FR 64S it has a Ortofon 2M black mounted (high compliance cart) and it sounds exceptional. Dynamic Tracking is set at 1.5g

In comparison i also have a SME 3010R with a AT ART9 mounted on a similar turntable and the 64S/2M combo sounds equally as good.

An alternative way to get damping for the arm and/or Decca is to mount them on a Townshend Rock turntable, which has a damping trough at the headshell end of the arm. The Townshend damping system also reduces the Q of the arm/cartridge resonance.

One can't ''balance'' the FR-64 with an lightweight headshell and

cart. The old FR headshell is worthless while the Orsonic AV 101

is much better than the (lightweigt) Orsonic AV-1. There are

different FR-64 counter weights but difficult to get. The nearer the

conterwight to the pivot the lesser the arm mass. The lighter the

the headshell the less arm mass. LPgear sells and excelent

headshell for about $ 50. There are different names and prices

for the same (magnesium) headshell which is made by Jelco(?).

I bought 6 of those under the name ''Sumiko'' for about 40 GBP a piece.
