Description

Brand New compatible drive chip we fit to failed Yamaha Disklavia TH3L20 drivers.

Specification almost identical to original specification and exact for the important values like operating voltage and current.

We’ve fitted these to various Yamaha pianos with no noticeable difference.

Symptoms requiring these chips to be replaced is 1 or more concurrent keys not playing electronically, but being told to play from the output of the logic chips.

It is also advisable to check the resistor network around the chip and ensure the coil is reading correct readings.

This part is brand new and sold with no warranty and is exempt from any warranty or requirement to offer a refund as it is not classed as a finished product and as such requires skilled fitting and soldering to make work. We sell these parts with the assumption the user has sufficient technical skill to carry out the work.

The picture is of an old removed unit which is defunct but demonstrated to show the compatible part
