ARP PSU repair KIT (Odyssey, Axxe, Explorer, Sequencer 1601...)

This kit contains ALL the parts needed to completely refurbish your ARP power supply. Sometimes finding parts to repair an electronic device takes a lot longer than diagnosing the failure. If you're not able to repair yourself, a technician will be very happy to repair it for you since finding parts is the time consuming part part.

The kit contains:
4 diodes 1N4448
2 transistors 2N3904
2 transistors 2N3906
2 transistors 2N6179 or TIP29A or D40D4
1 integrated circuit µA723 voltage regulator
2 trimpots 100K lin
2 capacitors 10µF 35V tantalum
2 capacitors 250µF 50V electrolitical axial terminals (2 plastic brackets included)
1 Fuse pigtail 125mA 250V slo-blow

Korg Delta DL-50 Filter repair Kit

The capacitors in the Korg Delta DL-50 will eventually prevent the synthesizer section from working.

This kit contains 4 units 1nF polypropylene orange capacitors, just like the originals (C21 to C24). After removing the KLM236 board, you should replace the LM13600N ICs. They also fail a lot. I am also including one pair of high quality machined IC sockets.

Kawai SX-210 CPU board repair kit

The Ni-Cad battery of this synthesizer is known for the damage it can cause. I rebuilt many of these boards and the solution is to change everything. Along with the components, complete printed schematics will be sent.

The kit contains:
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 (your unit may come with a MSM5128 - they work the same)
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.
