1 pcs. Replacement rotary potentiometer suitable forRoland MC 303Roland MC 505Electrical properties:The nominal resistance has 10 Kilo-Ohm, the electric resistance gradient is linear. The potentiometer is construed for a power of 0,05 Watt.Appearance (technical characterisation):The casing measures 10,5 x 11 mm, the total length without pins is 26,5 mm. In this total length the casing is 10 mm long. On this casing is the thread with 5 mm length connected and out of the thread the axis rises with 12,5 mm length. The axis has a diameter of 6 mm and is flattened on a length of 7 mm. It is made of Metall. Its head has ends in corner radius. The thread, which surrounds the axis, has the screw measure M9 x 0,75 mm.The three solder pins are 0,6 mm wide (one of them) and they are arranged in one row in a distance of 2,5 mm (pitch).At the end of the casing the metallic snap in connector is mounted. These connector will fix the potentiometer at the printed circuit board by pressing in.Between the two snap in holdings the distance is 10,5 mm. The holders latch in the board and fix the potentiometer mechanically.Useful hint:The Potentiometer is soldered on the circuit board. You should have mechanical skills and experience in soldering to replace it.

1 pcs. Roland MC303 and MC505 Encoder Board newThis Encoder PCB is suitable forRoland HP-557Roland MC303Roland MC505Mechanical Description of Roland MC505 Encoder Board:Roland used a Panasonic encoder with the designation EVQ-VEM-F01-24B in the above instruments. The production of this encoder at Panasonic was stopped many years ago.We have developed an adapter board on which a today's common encoder is soldered. This adapter board is soldered directly onto the Roland electronics.The switching feel is a bit harder with this new encoder than with the original.The new encoder has a metal housing and a plastic axle. Practical advice for Mounting MC303 Encoder :The encoder is permanently soldered onto a circuit board. Manual skills and experience in soldering are required for replacement.
