ARP Odyssey Mk I II and III Capacitor & IC Replacement Kit Models 2800 – 2823

Description

This kit contains replacements for all the polarized (tantalum and electrolytic) capacitors, and all CMOS ICs, Operational Amplifiers, and voltage regulators in the ARP Odyssey synthesizer.  This kit covers all models of the ARP Odyssey: Mk I, Mk II, and Mk III, Models 2800-2823, PPC or no PPC installed, just not the Korg remake!

If your synthesizer has not yet been recapped or is broken 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. The original CMOS chips and op amps used in these synthesizers are prone to failure. We find it a best practice to replace all these chips in this keyboard to fix issues it may be having and to prevent future issues from popping up as chips fail.

We provide quality, name brand, long life components. 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 and ICs you will need for the entire keyboard, including the power supply with the exception of the VCF submodule, as there are several variants depending on model. We offer a rebuild kit for the 4075 VCF submodule separately, which includes capacitors plus the necessary parts to correct a design error which limited the frequency response of the 4075 VCF to 12kHz. Users who have installed this modification have reported a very noticeable improvement in sound.  The LM301 op-amp is obsolete in through-hole form.  Rather than sending sketchy or ancient “NOS” chips, we include new, genuine surface mount LM301s pre-soldered to a DIP adapter.  Machine pin headers are included, and you will need to solder them onto the boards.

This product requires disassembly of the synthesizer and soldering skills to install. Please contact us if you require installation services.
