“HERE IS A VINTAGE SEQUENTIAL CIRCUITS INC. DRUMTRAKS DRUM MACHINE. IT NEEDS SOME TYPE OF REPAIR.
SOMETIMES WHEN I TURN THE SWITCH ON, THE RUN STOP LIGHT LIGHTS UP, THE LOAD CASSETTE LIGHT LIGHTS UP, THE SELECT SONG FUNCTION SONG NUMBER INDICATOR LIGHTS UP AND THE PATTERN NUMBER LIGHTS UP.
WHEN I SHUT IT OFF AND TURN IT BACK ON, THE LOAD BUTTON WILL FLASH. DIFFERENT LIGHTS WILL FLASH ON THE UNIT AND NOTHING WILL HAPPEN. I TURN IT ON AGAIN AND THE LEFT INDICATOR UP ABOVE THE KEYPAD FLASHES ZERO.
IT DOES ALL KINDS OF THINGS EACH TIME I TURN IT ON AND OFF. I AM NOT SURE IF IT HAS TO DO WITH THE SWITCH OR WHAT.
I LOOKED INSIDE THE UNIT AND NOTICED ON THE LEFT SIDE BY WERE IT HAS 3 LARGE BLACK CAPACITORS ARE, THERE IS A TRANSISTOR THING THAT HAS SOME CORROSION ON IT. I AM NOT SURE IF THAT AFFECTS THE UNIT. I NOTICED THERE ARE SOME SCREWS MISSING ON TOP THAT HOLDS THE PRINTER CIRCUIT BOARD ASSEMBLY TO THE TOP OF THE COVER, IT HAS A BUNCH OF CHIPS IN IT THAT SAYS BASS, SNARE, RIM, TOM, RIDE 4, HAR, PERC2 PERC1, RIDE 3, RIDE 2, RIDE 1 AND CRASH 1,2,3,4. THERE IS A STAMP THAT SAYS MAY PEACE PREVAIL ON EARTH.
IT LOOKS LIKE THE CIRCUIT BOARD MAY NEED TO BE CLEANED UP. I CAN SEE LIGHT CORROSION ON DIFERENT CIRCUITS ON THE UNIT. MAYBE IT WAS EXPOSED TO SOME MOISTURE OR IT IS JUST FROM AGE.
I AM SELLING THIS UNIT AS IS FOR PARTS OR REPAIR. EVERYTIME I TURN THE SWITCH ON IT DOES SOMETHING DIFFERENT. SOMETIMES IT DOES NOT TURN ON AT ALL.
THE METRONOME KNOB HAS BEEN CHANGED OUT FOR A DIFFERENT KNOB. IT IS MISSING A COUPLE OF SCREWS THAT HOLD THE COVER ON.” Link
