"I purchased this 23 years ago as an investment.When I received it was fully functional and I was able to nail a bass patch that sounded every bit as powerful as any Moog I've ever heard.After a year it stopped functioning and I Opened it up and noticed the filter was potted with epoxy to safeguard anyone copying the circuit but also prevents service.I packed it back up and it has been in storage until now.I was considering sending it to discrete synthesizers (CMS) for service but there are quite a few options that would improve upon the existing instrument but I should leave that up to the end user how it should be hot-rodded..."

Update: See the comments below for some debate over why the filter was encapsulated.

  1. Please stop spreading false information. The Filter and other ARP submodules CAN be repaired.
    And they were NOT encapsulated to prevent copying. They were encapsulated for mechanical and thermal stability.

    1. Mechanical stability issues? One of the objectives of encapsulating a submodule was to prevent copying, that's never been debated. ARP changed their encapsulation process and abandoned it over the course of the years. I've seen 2600 filters that are a solid block that you would be better off replacing than trying repair.
