Fixing one of the two DMX15-80S of the famous Motorbass Studio in Paris . Works perfectly now! Pots aren't scratchy anymore, and no more digital audio garbage since all boards' edge contacts have been cleaned and cards have been re-seated. . ...and a little clean-up of the front panel is on the house ;-) . #AMSNeve #DMX1580 #DMX1580S #AMSDMX1580S #VintageDigitalFXBox #VintagePitchShifter #VintageDigitalDelayLine #Repair #Fix #VintageElectronics #EarlyDigital #Motorbass #MotorbassStudio #MotorbassRecordingStudio #MotorbassParis #StudioPiscineATokyo #PiscineATokyo #TheGoodDoctorPrager

Capricieuse alimentation de 252 !!!! 😡 Mais après maints tests et mesures, elle est rentrée dans l'ordre... sans doute grâce à l'esprit de Serge G. qui plane toujours dans le studio Motorbass, près de 30 ans plus tard ! ^^ #EMT #ElektroMessTechnik #EMTFranz #EMTStudiotechnikGmbH #EMT252 #VintageDigitalReverberation #Repair #MotorbassStudio #MotorbassParis #MotorbassRecordingStudio #StudioPiscineATokyo #TheGoodDoctorPrager (à Motorbass Studio)

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

. . Restoration of @motorbass 's @eventideaudio H910 (cont') . Last minor step before alignment: rebuilding the previously installed modification that allowed connecting audio signals directly on the front panel by means of three standard jack sockets . As the holes drilled for them into the thick, steel metal panel are of course permanent, I found it somewhat neatier just to replace the old school, open jack sockets (clearly designed for studio patchbays) with more modern, new "half-closed" chassis sockets that not only protrude much less than the old ones, but also look more elegant! 👌(decoration flat-head screws also had to be installed: even if the new jack sockets do not need them in order to be attached to the panel, the corresponding empty holes would have "destroyed" the elegance of the mod in this new version! 😉) . The old inner cables linking the sockets to the analog PCB have also been replaced with new ones that use aluminum, 100% isolating shield (instead of the much leaky braid in the old cables) 👌(this is particularly important, given the fact that those cables run very close to the radiating power transformer... fortunately the unit has the optional in/out balancing transformers 😊) . #Eventide #EventideInc #EventideAudio #Harmonizer #H910Harmonizer #EventideH910 #EventideHarmonizer #EventideH910Harmonizer #VintageDigitalPitchShifter #VintageHarmonizer #VintageDigitalFXBox #EarlyDigital #Restoration #Repair #Fix #VintageElectronicsRestoration #ElectronicsRestoration #VintageElectronicsRepair #Motorbass #MotorbassStudio #MotorbassRecordingStudio #MotorbassParis #StudioPiscineATokyo #PiscineATokyo #TheGoodDoctorPrager #LeBonDocteurPrager https://www.instagram.com/p/Bpd-q3RBj8O/?utm_source=ig_tumblr_share&igshid=1gxl7peq29yso

. . Restoration of @motorbass 's @eventideaudio H910 (cont') . Still in the ninth step (troubleshooting)... but it looks like we're finally getting somewhere, at last!!! ☺️☺️☺️ . After finding a few dead op-amps in the D/A section, as well as the previously replaced 74C73 flip-flop on the digital board, it seems that the illness of this (1977) H910 has been mostly cured... 😊 . (not completely though, as there are still some minor "bugs" here and there to fix, and there will also be the final, tenth step to go: alignment 😉) . @eventidefrance @eventideitalia . #Eventide #EventideInc #EventideAudio #Harmonizer #H910Harmonizer #EventideH910 #EventideHarmonizer #EventideH910Harmonizer #VintageDigitalPitchShifter #VintageHarmonizer #VintageDigitalFXBox #EarlyDigital #Restoration #Repair #Fix #VintageElectronicsRestoration #ElectronicsRestoration #VintageElectronicsRepair #Motorbass #MotorbassStudio #MotorbassRecordingStudio #MotorbassParis #StudioPiscineATokyo #PiscineATokyo #TheGoodDoctorPrager #LeBonDocteurPrager https://www.instagram.com/p/BpbmEq_hxAf/?utm_source=ig_tumblr_share&igshid=1tnoofjp2scgw

. . Restoration of @motorbass 's @eventideaudio H910 (cont') . Continuation of the eighth phase: HD910 board has just been recapped, new IC sockets and new trimmers have been fitted in. .

Preliminary diagnosis of Motorbass Studio's H910 (cont'): first glance at the guts of the machine . A multi-image picture showing some of the more or less severe conditions endured by this unit during these 42 years... . From top left to bottom right: - very old Texas Instruments' TMS4060 DRAM chips: a sign that this might be a very early production unit. Wouldn't be surprised that some of them were dead, given the awful sound that this machine outputs for itself... - internal Feedback Level trimmer was replaced with too big a Piher one, then a jumper had to be added... - not surprisingly, both (usually running very hot) rectifier bridges were soldered too close to the PCB... - U20 (originally a 74C32 quad 2-input OR gate) on the Digital Board was replaced with a CD4071 which had to be jumpered because pinouts are different... - IEC mains inlet was replaced (probably for a good reason), but soldered wires were not shrink-tubed... - last, but not least: the hand-written (with pencil) signature of THE Master of the H910: Anthony... himself! 😊 . #Eventide #EventideInc #eventidestompboxes #Harmonizer #H910Harmonizer #EventideHarmonizer #EventideH910Harmonizer #VintageDigitalPitchShifter #VintageHarmonizer #VintageDigitalFXBox #EarlyDigital #Repair #Motorbass #MotorbassStudio #MotorbassRecordingStudio #MotorbassParis #StudioPiscineATokyo #PiscineATokyo #TheGoodDoctorPrager

Fixing one of the two DMX15-80S of the famous Motorbass Studio in Paris . Clearly looks like this RAM card has had power supply issues... which may have been caused by excessive oxydization of the card's edge contacts and its corresponding PCB connector. . Just thoroughly cleaned this board's contacts. Let's now do a complete clean-up of all cards' edge contacts and see if that solves the audio garbage that randomly appears at both outputs from time to time... . #AMSNeve #DMX1580 #DMX1580S #AMSDMX1580S #VintageDigitalFXBox #VintagePitchShifter #VintageDigitalDelayLine #Repair #Fix #VintageElectronics #EarlyDigital #Motorbass #MotorbassStudio #MotorbassRecordingStudio #MotorbassParis #StudioPiscineATokyo #PiscineATokyo #TheGoodDoctorPrager
