Synthchaser #061 – ARP Fender Rhodes Chroma Dual Footswitch Pedal Servicing
The pedal is for sale if you are interested, please contact me.
It’s not just your vintage synths that need love from time to time, it’s also their accessories. I service a Rhodes Chroma dual footswitch by replacing the damaged plug, cleaning the switches, recapping the switch, and polishing the brass. Result is a pedal someone will be proud to plug into their Rhodes Chroma.

Synthchaser #059 – Oberheim OB-8 Calibration Procedure & Demo
In the previous video we installed the Synthchaser OB-8 Voice Board Rebuild kit, which replaces the dried up electrolytic capacitors, dodgy trimmer pots and noisy resistors that can prevent an OB-8 from autotuning and sounding consistent from voice to voice.
In this video I show you how to perform a full calibration of the OB-8 and demo some of the sounds of the completed synth.

Synthchaser #057 – Oberheim OB-8 Power Supply Rebuild & Dead Oscillator
I show you around the inside of an Oberheim OB-8, and we take a look at a dead oscillator which is causing autotune to fail for one of the voices. Then, I install my power supply rebuild kit, which replaces the power supply capacitors and beefs up the bridge rectifiers.
The kit I’m installing is:
Synthchaser #055 – ARP Pro/DGX Mk I (Pro Soloist III) Repair – Infinitely sustaining notes
I repair an ARP Pro/DGX Mk I with a bad slider and certain voices that sustain indefinitely. And experiment with video editing and speeding up the video so you can see me solder!

In this video, I give a demonstration to show the features and sounds of the ARP Omni 2 polyphonic analog synthesizer.
Synthchaser #052 – ARP Omni 2 Troubleshooting & Repair – Dead Voices
In this video I repair a broken ARP Omni 2 where 2 of the 8 voices were broken (Violin and 4′ Synthesizer). I show how the synthesizer works and where common problems are that can cause dead voices and dead ranges of keys. We track down the problems on this keyboard with the oscilloscope and bring it back to working order.
