  • Yamaha CS-10 Sub Octave Mod

    The Yamaha CS series has some unique features inside and out. Most of the circuitry uses quite unusual IC’s (custom perhaps?) . The VCO for a start uses an interesting method of resetting the core, I can’t really go into detail because I can’t exactly understand what is going on but it creates a very stable oscillator that was used in the polyphonic part of the CS series. It has quite a pleasant band-pass filter and very fast attack settings, it can sound a bit sterile but its unique-ness pays off for that.

  • EDP Wasp Deluxe Repair

    The Wasp Deluxe was an enhancement on the original Wasp, they removed the touch keyboard, put it in a big wooden case with a real keyboard and added an oscillator mixer and an external audio input and that was about it. The component designators (IC1… IC2…C1…R100 etc) are all the same as the original wasp.

  • Roland Chorus Echo SRE-555 Repair

    This was a Roland Chorus Echo SRE-555 in a desperate need of service, It was bought second hand from Japan and was damaged in transit. It is actually just a Roland RE-501, but enclosed in a more compact 19” rack-mount case. For some unknown reason the SRE-555 usually costs more than a standard RE-501 in second hand prices, possibly because of its rarity or the fact it will fit into a studio better with its robust case.
