For sale a rare and excellent Koetsu Urushi MKI. This is cartridge is quite different from the present Urushi line. It was the top of the Koetsu line when it was released and the first to use platinum magnets. It also has genuine Urushi lacquer on a solid metal case unlike current Urushi who have wood bodies. This was the last and finest cartridge Sugano San made himself - his swan song. It easily compares to the stone bodies. I have collected two of these models over many years of searching but I must let one of them go now. This cartridge has been tested and works splendidly. It is in original condition and has only been lightly used. The original box is included. This is an opportunity to have a cartridge built by Koetsu founder Sugano san.


Here is some history this cartridge:

Urushi Mk 1

"The Urushi Mark 1 is essentially Sugano San's swan song product and a stunning example of Japanese decorative art deemed far too expensive to reproduce on the later " Mark 2 " Urushi models. Unusually the Mark 1 Urushi body shell appears on generators from several different series. Body dimensions for sample cartridge are Length 24.23mm, Width 9.47mm, Height 13.97mm rear, 15.24mm front, Weight 13g, Coil resistance 3.5 Ω, Output level 0.56 mV @ 1,Hz 5cm/s, Compliance ( sample ) 8.4 cu. Vertical Tracking Force 1.8 to 2 g. The body comprises an aluminium framework coated in a thick layer of Urushi tree resin and finally the decorative finish applied . This differs from later Urushi models which comprise the Urushi resin on a rosewood body. This was the first model to incorporate platinum magnets to control eddy currents. Urushi lacquer is a natural material made from the sap of trees grown in East Asian countries. The Urushi is in very limited supply. The deciduous Urushi tree takes 15 years to reach maturity and each mature tree can only supply 200 grams of sap. The Urushi sap (which is poisonous) is then mixed with other compounds to form the lacquer. If applied to a surface and kept in high humidity it slowly sets (hardens) into a hard, durable, waterproof and lustrous finish which is resistant to most other materials."
