Micro Seiki MA-505

Dynamic Balanced Universal Tonearm

Description

The MA-505, an ideal dynamic balance type tonearm, permits tracking force to be applied linearly during playback.

The spring tracking force application system which allows linear tracking force adjustment between 0.25-3g, is totally uninfluenced by factors such as turntable location conditions or record pressings.

Furthermore, at low tracking force settings, the tracking is exceptionally stable - resulting in unsurpassed performance with high compliance cartridges.

Precision spring and tungsten wire ensure long life and unchanging accuracy.

Lateral Balance Weight for MA-505

Submitted on August 1st, 2009 by Yosh

There were two types: A (lighter) & B (heavier).
I suppose B weighs double of A.
The specification of my weight B (as I thought being second-hand):
inner hole diameter 3mm, outer diameter 13.8mm, thickness 7.5mm
Weight 8.43g as measured.
Maybe the material is brass painted with black.

But as user of MA-505 I never meddled with this balance weight
simply mounting it nearest/shortest to lateral balance shaft. Also manual says as follows:
"When the player unit is perfectly level there are no problems whatsoever regarding lateral balancing". Hence better check your plinth with spirit level meter etc.

I hope this may help you somehow.

Regards
Yosh

MA 505 wire

Submitted on July 13th, 2009 by mosin

Hi Ymansiu,

You may want to try copier corona wire. It is available in various sizes, and most is gold plated tungsten. Years ago all copiers used this wire, and replacement was routine. There are still vendors around who have it. Maybe even a local copier shop will have some, or be willing to get it for you.

Best,
Win
