. . Next on the bench is @mathieusbrodenius 's #Eventide #H910 #Harmonizer . Complete restoration is on order for this unit which came from the great land of Sweden 😊 . Among its issues: two of the four ganged switches (of the "Pitch Control Select" group) are broken, PSU is to be wholy rebuilt (of course), one digit on the display misses one of its bars (rendering some numbers hard to read), the machine has audio faults in the digital section (not surprisingly...), is out of alignment, and is presently missing the dbx card for the "Delay Only" output. . ...another H910 restoration project for the Good Doctor Prager: so stay tuned! 😉 . @eventideaudio @eventidefrance . #EventideInc #EventideAudio #H910Harmonizer #EventideH910 #EventideHarmonizer #EventideH910Harmonizer #VintageDigitalPitchShifter #VintageHarmonizer #VintageDigitalFXBox #EarlyDigital #Restoration #Repair #Fix #VintageElectronicsRestoration #ElectronicsRestoration #VintageElectronicsRepair #StudioPiscineATokyo #PiscineATokyo #LeBonDocteurPrager #TheGoodDoctorPrager https://www.instagram.com/p/BuyC5kNFmGZ/?utm_source=ig_tumblr_share&igshid=1bh1kc1ln2li8

. . @melodiumstudio 's #Eventide #H949 #Harmonizer is finally fixed and fully aligned: notably in and out levels, as well as the feedback path are now all consistent and back to normal 😊 (also corrected the displayed range of pitch shifting 😉) . The vintage digital FX box is ready to go home in Montreuil then 😉 . @eventideaudio @eventidefrance . #EventideInc #EventideAudio #H949Harmonizer #EventideH949 #EventideHarmonizer #EventideH949Harmonizer #VintageDigitalPitchShifter #VintageHarmonizer #VintageDigitalFXBox #EarlyDigital #Repair #Fix #ElectronicsRepair #VintageElectronicsRepair #StudioMelodium #MelodiumStudio #StudioMelodiumMontreuil #MelodiumMontreuil #StudioPiscineATokyo #PiscineATokyo #LeBonDocteurPrager #TheGoodDoctorPrager https://www.instagram.com/p/Bs7pUMAjCle/?utm_source=ig_tumblr_share&igshid=mfhhujhjd7zw

. . This is one frequent "Achille's heel" in the #Eventide #H949 #Harmonizer : an almost dead AD7531, one of the two 12-bit DA converters used on the outputs, on the upper digital board. . The one for the Delay Only output (of the H949 of the @melodiumstudio in Montreuil) was effectively distorting the audio at very low levels... and also added a somewhat perceivable background noise all the time 😔 . Now that it's been replaced by a new chip, distortion AND hiss have disappeared. Meaning that the dynamic range of the Delay Only output has returned to its full spec 😊👌 . @eventideaudio @eventidefrance . #EventideInc #EventideAudio #H949Harmonizer #EventideH949 #EventideHarmonizer #EventideH949Harmonizer #VintageDigitalPitchShifter #VintageHarmonizer #VintageDigitalFXBox #EarlyDigital #Repair #Fix #ElectronicsRepair #VintageElectronicsRepair #StudioMelodium #MelodiumStudio #StudioMelodiumMontreuil #MelodiumMontreuil #StudioPiscineATokyo #PiscineATokyo #LeBonDocteurPrager #TheGoodDoctorPrager https://www.instagram.com/p/BsoeiXQh0X0/?utm_source=ig_tumblr_share&igshid=5cs1mtrfrz4g

. . Mr. @zdar_war testing his restored @eventideaudio #H910 #Harmonizer in the famous @motorbass studio in Montmartre, Paris. . He's looking particularly happy. Aren't you, Philippe? 😉😊👍 . ...and @pnantoine likes the 1977 FX box too, by the way 😊 . #EventideInc #EventideAudio #H910Harmonizer #EventideH910 #EventideHarmonizer #EventideH910Harmonizer #VintageDigitalPitchShifter #VintageHarmonizer #VintageDigitalFXBox #EarlyDigital #Restoration #Repair #Fix #VintageElectronicsRestoration #ElectronicsRestoration #VintageElectronicsRepair #Motorbass #MotorbassStudio #MotorbassRecordingStudio #MotorbassParis #PhilippeZdar #StudioPiscineATokyo #PiscineATokyo #LeBonDocteurPrager #TheGoodDoctorPrager https://www.instagram.com/p/BrFuY4LIDdY/?utm_source=ig_tumblr_share&igshid=1mcqm9t4yta2u

Back to @ratossentos 's H910 restoration . During the last step (that is, the alignment) there was no way to internally adjust the "MIN" pitch setting down to ".50" (as is normally expected on an H910): probably due to component value drifting over many decades of use (and certainly also to overheat), display and pitch-shifting couldn't be decreased under ".53" (moreover, with extreme settings of the internal trimmers!)... 😟 . So, after having replaced all involved trimmers with fresh-new ones (all of the cermet type), I'm manually determining the correct value for the biasing resistance that's in series with the "Min F" internal trimmer (responsible for the minimum allowable pitch-shifting). Thanks to my (very handy) Precision Variable Decade Resistance box, that's just a piece of cake! 😉 . @eventidefrance @eventideaudio @eventideitalia . #Eventide #EventideInc #EventideAudio #Harmonizer #H910Harmonizer #EventideH910 #EventideHarmonizer #EventideH910Harmonizer #VintageDigitalPitchShifter #VintageHarmonizer #VintageDigitalFXBox #EarlyDigital #Restoration #StudioPiscineATokyo #PiscineATokyo #TheGoodDoctorPrager #LeBonDocteurPrager https://www.instagram.com/p/BqHa9n2l8KT/?utm_source=ig_tumblr_share&igshid=1r9yuwax9abej

Last vid before moving on to some other unit to fix: looks like Mister @zdar_war 's machine is working... like a charm! 👌😊👍☺️😍 . #EventideInc #EventideAudio #H910Harmonizer #EventideH910 #EventideHarmonizer #EventideH910Harmonizer #VintageDigitalPitchShifter #VintageHarmonizer #VintageDigitalFXBox #EarlyDigital #Restoration #Repair #Fix #VintageElectronicsRestoration #ElectronicsRestoration #VintageElectronicsRepair #Motorbass #MotorbassStudio #MotorbassRecordingStudio #MotorbassParis #StudioPiscineATokyo #PiscineATokyo #LeBonDocteurPrager #TheGoodDoctorPrager https://www.instagram.com/p/BqF2iimhgTD/?utm_source=ig_tumblr_share&igshid=psmr6a8634nj

. . @motorbass 's #Eventide #H910 #Harmonizer restoration (cont') . In and out XLR adapter cables have also been professionally rebuilt with correct connecting blades for attaching them to the rear, old-fashioned terminals 😊 . #EventideInc #EventideAudio #H910Harmonizer #EventideH910 #EventideHarmonizer #EventideH910Harmonizer #VintageDigitalPitchShifter #VintageHarmonizer #VintageDigitalFXBox #EarlyDigital #Restoration #Repair #Fix #VintageElectronicsRestoration #ElectronicsRestoration #VintageElectronicsRepair #Motorbass #MotorbassStudio #MotorbassRecordingStudio #MotorbassParis #StudioPiscineATokyo #PiscineATokyo #LeBonDocteurPrager #TheGoodDoctorPrager https://www.instagram.com/p/BqFDxx5lwCw/?utm_source=ig_tumblr_share&igshid=kiu0cis1mfdv

. . @motorbass 's #Eventide #H910 #Harmonizer restoration (cont') . Complete alignment, the eleventh and last (but not least) step of this restoration project, is over: unit is now ready to go back to the famous parisian studio! 😊 . By the way, isn't its front panel beautiful, almost like new?👌 . (I guess #TheGoodDoctorPrager 's magic has worked... ☺️) . #EventideInc #EventideAudio #H910Harmonizer #EventideH910 #EventideHarmonizer #EventideH910Harmonizer #VintageDigitalPitchShifter #VintageHarmonizer #VintageDigitalFXBox #EarlyDigital #Restoration #Repair #Fix #VintageElectronicsRestoration #ElectronicsRestoration #VintageElectronicsRepair #Motorbass #MotorbassStudio #MotorbassRecordingStudio #MotorbassParis #StudioPiscineATokyo #PiscineATokyo #LeBonDocteurPrager https://www.instagram.com/p/BqFC0x9FpLH/?utm_source=ig_tumblr_share&igshid=8rszhhn8769x
