The restoration work went beyond cleaning and refinishing. The original wiring harness had too much damage to trust, several switching components were beyond recovery, and parts of the multimode filter needed active repair.
One of the most practical updates was replacing the original tinijax hardware with new Switchcraft 35PM2A jacks. That makes the system easier to patch with modern 3.5mm cables and lets it play more naturally with Eurorack gear.
- Replaced all jacks with new Switchcraft 35PM2A hardware.
- Used NOS Raytheon switches where originals could not be saved.
- Used NOS Clarostat, Ohmite, Allen-Bradley, and Precision Electronics K-series potentiometers as needed.
- Reconditioned the power supply capacitors and rebuilt the full wiring harness.
- Replaced the failed Q feedback regulation OTA in the multimode filter.
- Replaced all tantalum and electrolytic capacitors in the modules, plus a few damaged ceramics.
- Sourced the missing second reverb tank to return the system to a complete configuration.
- Filled the empty second VCO slot with a module from the collection.
- Added three new VCO modulation inputs: AC-coupled 1V/Oct, AC-coupled linear FM, and DC-coupled linear FM.
The result is not just a cleaned-up cabinet. It is a working system rebuilt for reliability, with a few carefully chosen changes that make it easier to use in a contemporary modular context.
