This kit contains replacements for all the polarized (tantalum and electrolytic) capacitors in the ARP Omni Mk 1 synthesizer. If your synthesizer has not yet been recapped, is broken, or has hanging or silent notes this kit is an essential starting point in any repair. The original low quality tantalum capacitors were prone to shorting out and were easily damaged by transient voltage spikes when turning on and off the keyboard. The original electrolytic capacitors have long since dried out and stopped performing as they should. This kit contains high quality electrolytic capacitors to replace these failed or failing capacitors and provide decades of stable operation.
We provide quality, name brand, long life capacitors. Axial capacitors are provided to replace axial capacitors, radial capacitors to replace radials. High temperature 105°C capacitors provided for the power supply section and voltage values were increased above the original where they will physically fit to ensure rock solid operation and long life.
This kit includes all the capacitors you will need for the entire keyboard, including the power supply and the 4075 VCF submodule with no nickel and diming! As a bonus, we also provide at no charge the necessary parts to correct a design error which limited the frequency response of the 4075 VCF to 12kHz, and the instructions to install it if you wish to do so. Users who have installed this modification have reported a very noticeable improvement in sound.
We also provide a checklist of the capacitors provided for each board, to reduce your time wasted poring over the schematics and scratching your head wondering where that last capacitor is supposed to go.
The Omni Mk 1 and Omni Mk 2 keyboards have slightly different architectures. We offer kits for both the Omni 1 and Omni 2, please be sure to order the correct one for your keyboard. This product requires disassembly of the synthesizer and soldering skills to install.
