This unit was recently fully restored/overhauled by repair shop, Synth Tailor Electronics in Columbus, Ohio. It’s in great cosmetic shape for its age. This H949 also had the de-glitch board that came on the latter models (this is the one you want for this model)!

Work/Restorations done:

-All Tantalum Capacitors replaced with new production Tantalum capacitors

-Power Supply Rebuilt (New Voltage Regulators, Molex Connector, Filter Capacitors, Upgraded Bridge Diodes)

-DBX Cards rebuilt and calibrated (electrolytic capacitors changed with Pansasonic/Nichicon 105 degree capacitors)

-Standard CMOS/OP Amps that are frequent failures in these Harmonizers replaced and socketed for future reliability

-Modified calibration trim pots in Feedback circuit for way more control (Added 25 turn sealed Bourns trim pots instead of single turn trimmers)

The feedback knob doesn't screech/ self oscillate at 12 o clock like they originally did from factory (this is Mod I learned from my tech friend/digital repair Guru Peter Foley from Foleytronics LLC)

-Allen Bradley potentiometers cleaned and lubricated, no scratchy pots
