How do you calculate effective tonearm mass?
Re: Measuring Tonearm Effective Mass M=Mass of headshell+cartridge+tonearm tube (11Gr.)
What is a medium compliance cartridge?
A Medium compliance cartridge suspension will be between “soft” and “firm”. This means it won’t like a heavy car body or a super light one to perform at its best. It will prefer a medium weight tonearm (car body) so the suspension can react nicely and evenly to the undulations of the road (record groove).
What is considered a high compliance cartridge?
A phono cartridge with the compliance in the range of 5 to 10 µm/mN is considered as a very low compliance cartridge, a cartridge with the compliance in the range of 10 to 20 µm/mN is moderate compliance cartridge and a cartridge with the compliance value above 35µm/mN is very high compliance cartridge.
How do you match a turntable cartridge?
The easiest way to know which cartridge you have on your turntable is to determine whether or not there is a headshell. What is a headshell? The headshell is a piece designed to attach to the end of a turntable’s tonearm. The cartridge is screwed into the slots on the headshell to hold it properly in place.
What is considered low output MC cartridge?
Output from carts can also vary a lot. Some LOMC have as little as 0.15mV out. Others can have 0.5mV. More gain in the phono stage makes that amplification more critical, especially with noise.
How long does a ortofon 2M Blue Last?
1000 hours
2M Blue Technical data Stylus lifetime: with proper care we find that up to 1000 hours is possible without degradation of performance.
What is a low mass tonearm?
* A tonearm whose effective mass is rated at 10 grams or below is considered low mass (e.g. early SME’s, Grace 747 etc.). A tonearm whose effective mass is rated between 11 and 25 grams is considered moderate mass (e.g. SME 309, IV, IV-Vi, V, Triplanar, Graham).
What is considered a high output MC cartridge?
A high output MC phono cartridge is also meant for the same standardized loading value as an MM cartridge: 47k ohms of impedance. If adjustable on your phono preamp, treat the input capacitance (measured in pF) similarly to an MM as well.
What is a Jelco tonearm?
Jelco tonearm models are made by the Ichikawa Jewel Company, which was established in 1920, as a manufacturer of the high-end audio plugs, as well as audio accessories. Their Japanese engineering is second to none (think Lexus). Jelco makes their own jewelled bearings and other parts in house and are in complete control of quality.
Which Kuzma tonearms to use instead of jelcos?
Among them were Linn (Basik and Akito), Audioquest (PT6), Koetsu, Sumiko, and Graham (Robin), to name a few. One overlooked substitution for the Jelcos is the lower range of Kuzma tonearms (the Stogi S) The success of the 4Point and Stogi Reference tonearms casts a bit of shade on the junior Stogi.
What is a good replacement for a Jelco?
One overlooked substitution for the Jelcos is the lower range of Kuzma tonearms (the Stogi S) The success of the 4Point and Stogi Reference tonearms casts a bit of shade on the junior Stogi. But Wait! Some SA-250s are still available!
