@redhousestudio_fr 's H910 is finally ready to go home: thoroughly cleaned (outside AND inside), power supply recapped and power transformer replaced, dead "LIMIT" LED replaced too... and correctly aligned, of course! 😊👌 . Big thanks to @lucasmedus , the owner of Redhouse (a superb, medium sized residential studio in the Champagne countryside, btw 👌😊) . @eventidestompboxes @eventidefrance @eventideitalia . . #Eventide #EventideInc #eventidestompboxes #Harmonizer #H910Harmonizer #EventideH910 #EventideHarmonizer #EventideH910Harmonizer #VintageDigitalPitchShifter #VintageHarmonizer #VintageDigitalFXBox #EarlyDigital #RedHouseStudio #StudioRedHouse #StudioPiscineATokyo #PiscineATokyo #TheGoodDoctorPrager #LeBonDocteurPrager

Finally found the time to align @tony_fine 's H910! ☺️ (was just kidding with the Bach cantata, please don't blame me, anyone ^^) . Now it's eventually ready for travelling back home 😉 . #Eventide #EventideInc #eventidestompboxes #Harmonizer #H910Harmonizer #EventideH910 #EventideHarmonizer #EventideH910Harmonizer #VintageDigitalPitchShifter #VintageHarmonizer #VintageDigitalFXBox #EarlyDigital #Restoration #StudioPiscineATokyo #PiscineATokyo #TheGoodDoctorPrager #LeBonDocteurPrager

Yeah, I hear you: "Another H910, once again!" But I just LOVE fixing these old little beasts, you know... 😉☺️ . This time, looks like @tony_fine 's Harmonizer is finally ready for alignment, after having replaced the power transformer and fixed a broken Molex connector (also in the PSU section). For sure it wasn't the only changes this piece has endured, meaning that it has come a looong way... but it's working now ☺️ . ...and, of course: sorry about that, dear Ludwig! ^^ . #Eventide #EventideInc #eventidestompboxes #Harmonizer #H910Harmonizer #EventideH910 #EventideHarmonizer #EventideH910Harmonizer #VintageDigitalPitchShifter #VintageHarmonizer #VintageDigitalFXBox #EarlyDigital #Restoration #StudioPiscineATokyo #PiscineATokyo #TheGoodDoctorPrager #LeBonDocteurPrager

Overhauling @onetwopassitstudio 's H910 (cont'): HD910 board's ICs all tested and reinstalled... looks like it's already working fine, despite it still has to be aligned "by the book" 😊 . Beginning to feel proud of this looong but worth-the-wait restoration... shouldn't I? ☺️ . #Eventide #EventideInc #eventidestompboxes #Harmonizer #H910Harmonizer #EventideH910 #EventideHarmonizer #EventideH910Harmonizer #VintageDigitalPitchShifter #VintageHarmonizer #VintageDigitalFXBox #EarlyDigital #Restoration #OneTwoPassIt #OneTwoPassItStudio #OneTwoPassItStudioBagnolet #StudioPiscineATokyo #PiscineATokyo #TheGoodDoctorPrager #LeBonDocteurPrager

Overhauling @onetwopassitstudio 's H910 (cont'): ...and the series continue! 😉 . HD910 PCB (dubbed the "Digital Board") is where the harmonizing effect happens! This is the CORE of the Eventide H910, the first commercial unit in history capable of real time pitch-shifting. Back in 1975-76, this was SUCH an achievement... and 42 years later, it still represents an amazing effort of fitting all the necessary wired-logic (no microprocessor or even a DSP in there! everything is made of standard logic ICs 👍) onto a 40x30cm printed circuit board. All hail Mr. Agnello! 👏👏👏👌👌👌 . The PCB has now been completely recapped, trimmers have been replaced, and a fresh-new ribbon cable with new DIL connectors has been fitted. Next step: testing all the socketed ICs before reinstalling them, and... it will be good to go! (not completely, though: alignment will obviously be on order before this H910 may leave the @piscineatokyo vintage clinic! 😉) . #Eventide #EventideInc #eventidestompboxes #Harmonizer #H910Harmonizer #EventideH910 #EventideHarmonizer #EventideH910Harmonizer #VintageDigitalPitchShifter #VintageHarmonizer #VintageDigitalFXBox #EarlyDigital #Restoration #OneTwoPassIt #OneTwoPassItStudio #OneTwoPassItStudioBagnolet #StudioPiscineATokyo #PiscineATokyo #TheGoodDoctorPrager #LeBonDocteurPrager

Overhauling @onetwopassitstudio 's H910 (cont'): One step beyond! 😊 . dbx boards are all three reinstalled, after they have been recapped and their ICs all tested. Also, the front panel has been cleaned and put back into place. . Last (but not least^^) step: taking care of the (upper) digital board, where the heart of the H910 is... ☺️ . #Eventide #EventideInc #eventidestompboxes #Harmonizer #H910Harmonizer #EventideH910 #EventideHarmonizer #EventideH910Harmonizer #VintageDigitalPitchShifter #VintageHarmonizer #VintageDigitalFXBox #EarlyDigital #Restoration #OneTwoPassIt #OneTwoPassItStudio #OneTwoPassItStudioBagnolet #StudioPiscineATokyo #PiscineATokyo #TheGoodDoctorPrager #LeBonDocteurPrager

Overhauling @onetwopassitstudio 's H910 (cont'): Going slowly but surely... 😊 . LEDs have been replaced with brigther ones, all regulators are back into place, HA920 PCB has been reinstalled into the cleaned chassis, power has been applied... and there it goes: so far so good! (you can see the LEDs are lit 😉) . Next two steps: the front panel and the HD910 board. . #Eventide #EventideInc #eventidestompboxes #Harmonizer #H910Harmonizer #EventideH910 #EventideHarmonizer #EventideH910Harmonizer #VintageDigitalPitchShifter #VintageHarmonizer #VintageDigitalFXBox #EarlyDigital #Restoration #OneTwoPassIt #OneTwoPassItStudio #OneTwoPassItStudioBagnolet #StudioPiscineATokyo #PiscineATokyo #TheGoodDoctorPrager #LeBonDocteurPrager

H910 recently fixed: here's the solution! A (NOS) MM74C08N quad 2-input AND gate to replace the original (1978-built) one that had gone bad ;-) . #Eventide #EventideInc #eventidestompboxes #Harmonizer #H910Harmonizer #EventideHarmonizer #EventideH910Harmonizer #VintageDigitalPitchShifter #VintageHarmonizer #VintageDigitalFXBox #EarlyDigital #Repair #ChipMasterCompact #ABIChipMasterCompact #DigitalICTester #StudioPiscineATokyo #PiscineATokyo #TheGoodDoctorPrager
