SY-1 Pearl Syncussion clone - fixing the PSU noise

Published on Jul 2, 2018 Stereoping

"The first batch of the brilliant SY-1 Syncussion clones from the human comparator seemed to have an issue with the negative power supply (TL497 inverter), soiling an ennoying high frequent noise into the audio path. There are several discussions and suggestions for fixing in different discussion boards. On learning from Shruthi filter schematics i came across another voltage inverter (LT1054) and wanted to give it a try. To my own surprise it worked right away, the noise completely disappeared, the unit still worked (unbeleivable!) and the new inverter keeps perfectly cool. I built a test setting with a switch allowing to flip from the original negative supply to a breadboarded LT1054 supply. You will directly hear and see the difference.

Second half of the demo shows some pictures how my alternative negative supply looks like now. It is soldered directly in place after removing the TL497 and some unused components. The background music is of course from the SY-1 (after PSU-conversion) together with the impOSCar.

There is an article on my site with more details about this hack."

Elka Solist 505 Vintage Italian Porn-tastic Analog Synthesizer SN 2779

"This very rare analog synthesizer features both presets and free control of key parameters sort of like an Italian SH1000 or Arp Pro Soloist (hmm, that name rings a bell), or Moog Satellite. According to the site "encyclotronic":
"A feature of the Soloist 505 is that it has the famous Moog Ladder Filter onboard. Manufacturers installed the components to make the Ladder Filter before Moog Music imposed a patent on it's use in non Moog instruments."

It's virtually identical to the synthesizer built into Elka's big double manual organ the X705 and has the same porn-tastic vibe ;)"

"The touch membrane is perfect. All knobs & buttons function as they should (the volume pot was a little scratchy until I exercised it, due to it always being set at the same spot)... Pictures are of actual synth/keyboard, both manuals, MOOG brochure of their synth lineup, and the MOOG purchase document from LMI - Lipham Musical Instruments in Gainesville, FL."

"Beautiful housing, all buttons intact - HOWEVER - was many many years unused and some combination of mechanics and electronics are now poor/unusable. Oscillators seem to work but feeble at best, there's a stuck-'on' key and there will need to be some serious diagnostics and repairs done to key triggers, pots and switches I assume, to get back to reliable playing quality."

If it's a j-wire version, the wires likely just need cleaning and bending. I once picked up a Pro-One from Guitar Center for $125 due to a stuck note. I opened it up, bent the j-wire back and it was as good as new. They way the keyboard works is there is a little wire that extends from them. When you press a key it tilts up and makes contact with a metal bar. If the wire is bent it can end up touching the bar producing a stuck note. If the wires and bar are oxidized or dirty for whatever reason, pressing notes can sound unstable. That said, if you pick this one up and it's not due to these issues do not blame me. :) Just throwing this out there for Pro-One owners with similar problems.
