Fully Restored Ensoniq EPS-16 Plus Digital Sampling Workstation

Up for sale is a meticulously restored, classic 16-bit Ensoniq EPS-16 Plus keyboard. I have restored and safely shipped hundreds of vintage keyboards over the years. This unit has been thoroughly overhauled, tested, and upgraded for modern workflows.

Mechanical & Electronic Restoration

• Deep Cleaned: Completely detailed inside and out.
• Circuit Board Reflow: Re-soldered known failure points across all internal boards to prevent future issues.
• Power Supply Verified: All voltage rails tested and verified within factory specifications per the official service manual.
• New Controls: Brand new Volume and Data slider potentiometers installed.
• Tact Switches Serviced: All buttons cleaned with DeoxIT; two faulty switches replaced due to failing membranes.
• Keybed & Aftertouch: Coil boards fully inspected and cleaned; polyphonic aftertouch functions flawlessly.

Chassis Cosmetic Refinishing

• Fresh Paint: The outer chassis top and sides were sanded smooth and refinished with two coats of high-quality Rust-Oleum 2X UltraCover Paint+Primer to cover deep original blemishes.
• Rear Port Labels: The original rear silk-screen labels were worn off and are no longer visible. A physical print-out diagram of the rear port layout is included so you can easily reference or create your own labels.

USB Floppy Emulator Upgrade

• Hardware: Brand new USB drive emulator installed featuring a crisp OLED display and a rotary push-button encoder for easy folder navigation.
• Firmware: Flashed with the latest FlashFloppy firmware (reads both .IMG and .HFE disk images).
• Included Storage: Loaded 32GB SanDisk low-profile USB drive containing a ~4.5 GB personal sample library collected over years, plus useful utility tools.
• Sample Libraries: Includes images for EPS (Classic/16), ASR-10, and Mirage.
• Note: This unit contains the standard 1MB of memory. Because the ASR-10 has larger memory limits, some included ASR-10 samples may not load. You can easily upgrade memory via the rear expansion slot at your own risk without opening the chassis.

Rigorous Testing & Functionality

The unit was soak-tested by being left powered on for several hours across three separate days. I successfully recorded a custom sequence using empty disk images on the USB drive. 100% functional coverage verified for:

• All tact switches, keys, and patch select buttons
• Pitch and mod wheels
• Volume and data sliders
• Sampling, sequencing, loading, and saving functions
• MIDI In/Out
• Headphone, main audio outputs, and sustain pedal inputs
• Polyphonic aftertouch

What’s Included
