I SOLD OVER 100 UNITS OF THIS KIT IN EBAY!

This is a set of all the components you will ever need to repair the Kawai (or Teisco) SX-210 micro computer board (SYN-42) known for the ni-cd battery leakage problem. I had a customer that brought me 9 (nine) units to repair, all with the same problem.

Beside repairing the board, you will be able to change for a stable lithium battery (included, as well as the components and instructions to do it). I will provide you a clean PDF service manual and some extra instructions (from advice on how to remove corroded components to reloading the factory presets, etc.). I will also provide you the banks' presets in .wav format and the instructions manual. This is not a task for beginners, you have to be able to solder and desolder 2 face PCBs. But you can take this kit to a local repair shop, and they will gladly do the job. The time consuming part is sourcing these components. I am always available to help fellow synth lovers. Try me.

The KIT contains all the parts next to the battery and some others that I used in some moment to repair the boards:

1 CPU Intel P8031 (this one is far from the battery, but I had to change it in some boards due to short circuits)
1 2764 Programmed EPROM with the last known firmware
2 ULN2003A darlington transistor array
1 SN74LS374N
1 µPD8253C NEC programmable interval timer
1 TC5517 Toshiba 2K RAM or a equivalent 6116 family RAM like Sanyo LC3517
2 transistors 2SA564
2 transistors 2SC536
1 zener diode 5.2V (WZ-052)
1 diode 1S2473
1 diode 1S1555 (to adapt the new lithium battery)
1 CR2032 lithium battery with soldering tags
2 resistor network 3,3KΩ x 8
2 2,2KΩ 1/4W resistor
7 3,3KΩ 1/4W resistor
6 electrolytic capacitors 10µF 16V
3 electrolytic capacitors 0.22µF 16V

1 electrolytic capacitor 47µF 16V
1 electrolytic capacitor 100µF 25V
all the integrated circuits come with a good quality machined DIL socket.

All the components are tested prior to shipping including the ESR of the capacitors.

I collect and repair synthesizers since 1992 and I really value this kind of stuff.  I've got parts for many synthesizers, check my other items. Pots for Korg, Elka, Moog, Roland and some Casio. Contact for help.

Free tracked shipping. I allways try to ship the same day if payment made before noon. I don't charge extra if you buy more than one kit.
