Wer kennt den Tonabnehmer "ma 2002"?

Hi UW,

Das dürfte ein MicroAcoustics Elektret-Tonabnehmersystem sein, da gab es eins mit der Bezeiochnung 2002e.
Viel ist darüber nicht bekannt, du kannst ja mal in diesen Thread im AAA-Forum schauen, da findest du etwas über einen Verwandten deines Systems.

Hallo UW,

ich benutze dieses gelegentlich auf einem Yamaha:

Habe auch irgendwo noch den Prospekt zu dem Teil.

Hallo,

bischen was an Info habe ich hier noch gefunden:

Zitat:

Micro Acoustics
Manufactured 2 distinct lines of pickups, one was MM based and consisted of mostly budget types, the other was based around ceramic elements developed from those manufactured by Sonotone in the 60's and while the company has some low/mid range models this ceramic line was more oriented towards te mid/high end and considered to be excellent at the time especially their bass response. Since all amplifiers had by this time a phono input with MM amplification and RIAA Eq. their pickups often contained revese Eq. circuit based around a tiny opamp (referred to as a computer by the company) so they could be used with those amps! You can also get some of the MA pickups and styli from Adelcom.net but note that the "average retail price" listed is actually 4 to 5 times the original RRP. Note that the details below are for 80's era carts but apparently earlier carts can use stylii intended for later carts for instance the QDC-1e can use a 300 series stylus note also that the 25 and 50 are p-mount carts that came with an adapter to use with standard mounts (at the least the later models), the company seems to have in the later years switched from 0,25 or 0,2 x0,7 elliptical stylii to a cheaper 0,3x0,7 so carts bought after 1984/5 may have that written in the specs rather than what is shown below, also note that we have had reports that replacement stylii from the late 80's that were sold under the company's name and commonly show up as NOS appear to have been incorrectly heat cured so the stylus falls off (this is only a problem if the stylus has been in storage for a few years, as all NOS stock has), so we would recommend for those that have a pickup to send the to a retipping service such as Garrott Brothers or Expert Stylus rather than hunting down a original stylus. The budget MM carts with a P in the name such as the PS and PE are P-Mount. There are also a couple of later cheramic models that I have been unable to track down any info on such as the 320.

The 2002e technical specification are : Element: Ceramic. Frequency response: 5Hz~20KHz +-1,5dB. Output @ 5cm/s: 3,5mV. Tracking force: 0,7 to 1,4 grams. Channel Seperation: 30dB @ 1KHz, 15dB @ 10KHz. Channel balance: +-1dB @ 1KHz, or less. Stylus Tip: Elliptical. Load: 10k to 100k ohms. Load Capacitance: 100pF to 500pF. Weight: 4 grams.

Vielen dank, da hab ich ja schon mal was zum Weiterforschen, ciao uw
