Looks like @fabcostello 's H3000 is calling in... very sick!!! π°π°π° . After having restored the front panel, I may now turn over to fixing the core audio issues. According to the sounds that the unit generates on its own (no analog audio signal is input), these faults seem to be caused by very low level digital logic troubles... . Let's hope I'll eventually find out the culprits! π . #Eventide #H3000 #EventideH3000 #H3000UltraHarmonizer #UltraHarmonizer #EventideH3000UltraHarmonizer #VintageDigitalFXBox #VintageDigitalOutboard #Repair #PlaneteSunStudio #PlaneteSun #PlaneteSunStudioPuteaux #StudioPlaneteSun #StudioPlaneteSunPuteaux #PlaneteSunPuteaux #StudioPiscineATokyo #PiscineATokyo #TheGoodDoctorPrager

JUST CAN'T BELIEVE IT MYSELF!!!! I MADE IT!!!!!!!!! @fabcostello 's H3000 is finally FIXED!!!!!!!!!!!!!!! πππππ . I am SO relieved, after all these dozens of hours studying the schematics and Theory of Operation from inside out, probing and measuring along the way, also comparing the signals with a working unit... all that to eventually find a small and VERY unfortunate solder bridge on the underside of the PCB, between just TWO pins of the 74HC374 octal D-type flip-flop that acts as one of the two "Delay Input Registers" of the Delay Memory section!!!! π‘ Was completely unspottable at first sight, not to mention that there are almost 200 chips in the H3000, so imagine the HUGE number of soldered pins to scrutinize... π¨π¨π¨ . Anyway, now that I've struck down the beast ^^, it seems that this @eventidestompboxes 's wonderful FX box of the late '80s has gone back to neat work, at last!!! ππππππβΊοΈβΊοΈβΊοΈ . #Eventide #H3000 #EventideH3000 #H3000UltraHarmonizer #UltraHarmonizer #EventideH3000UltraHarmonizer #VintageDigitalFXBox #VintageDigitalOutboard #Repair #PlaneteSunStudio #PlaneteSun #PlaneteSunStudioPuteaux #StudioPlaneteSun #StudioPlaneteSunPuteaux #PlaneteSunPuteaux #StudioPiscineATokyo #PiscineATokyo #TheGoodDoctorPrager
