We install 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.

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!
Synthchaser #054 – ARP Omni 2 Disassembly
I show how to disassemble an ARP Omni 2 and remove all the circuit boards and the power supply. You can send your boards to me for recapping, service or repair so you can have an expert repair your synth without having to ship the whole heavy thing!
Synthchaser #053 – ARP Omni 2 Demonstration
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.

Synthchaser #050 – ARP 2600 Grey Meanie Troubleshooting & Power Supply Rebuild
I begin the restoration of a very rare (one of ~35 made) ARP 2600 Grey Meanie. I bought this ARP totally dead and intend to do a full restoration of it before I sell it.
Its previous owner thought the power supply was broken, so we check it out and locate the real problem. But, as should be done with every vintage synth, we rebuild the power supply.
If you’d like me to make more videos as I repair and restore this ARP 2600, please let me know!
Synthchaser #049 – Yamaha SK10 Symphonic Ensemble Servicing & Demo
I give a quick demo of the functionality of the Yamaha SK-10 analog synthesizer, and perform a light service on it–cleaning switches and sliders and recapping the power supply. This keyboard is currently for sale on my site.
Synthchaser #048 – Tim’s ARP Omni 2 Restoration & Repair
I restore Tim’s broken ARP Omni 2, rebuilding the power supply, replacing all the polarized capacitors, enhancing the filter, adding my LED sliders, and refurbishing the keybed.
