Final step completed: reverb programs version 1.3 installed and working fine! 👌👍😊 . #LexiconInc #LexiconM200 #Model200 #LexiconModel200 #DigitalReverberator #VintageDigitalReverb #EarlyDigital #Repair #VintageElectronicsRepair #VintageProAudioEquipment #StudiosSodasoundParis #SodasoundParis #SodasoundStudios #SodasoundStudiosParis #StudioPiscineATokyo #PiscineATokyo #TheGoodDoctorPrager #LeBonDocteurPrager https://www.instagram.com/p/Bt5gz6JlJMK/?utm_source=ig_tumblr_share&igshid=cuykusq9egzr

. . Emergency case for @sodasound studios' #LexiconPro #M200 (cont') . After having replaced the corroded resistors and the "NMI CAL" trimmer, and after having soldered the correct battery for the job DIRECTLY onto the PCB (Lexicon even provided the board with different footprint patterns for different battery form factors! 👍), the unit finally starts up fine each time and does not randomly reboot on itself anymore 😊😊😊👌👌👌👍👍👍 . While I was at it, I checked the Z80 CPU. As it failed to pass the tests of my trusty #ChipMasterCompact #ICTester, I decided to replace it, as well as its old socket 😉 . Also took two pictures of the newly soldered components from the underside of the board... so you might just have a peek at my solder job ☺️ . #LexiconInc #LexiconM200 #Model200 #LexiconModel200 #DigitalReverberator #VintageDigitalReverb #EarlyDigital #Repair #VintageElectronicsRepair #VintageProAudioEquipment #StudiosSodasoundParis #SodasoundParis #SodasoundStudios #SodasoundStudiosParis #StudioPiscineATokyo #PiscineATokyo #TheGoodDoctorPrager #LeBonDocteurPrager https://www.instagram.com/p/BtsxOgYlfTp/?utm_source=ig_tumblr_share&igshid=1wyf1n8e6d88f

. . Emergency case for @sodasound studios . Their #LexiconPro #M200 has an annoying issue at start-up: front panel frequently blinks with all LEDs and digits lit, and sometimes it just stays blank, and nothing happens... At other times, the unit starts up fine, but the panel begins to blink (in the same way) all of a sudden! 😨 . No wonder why after having inspected the interior of the machine: old leaking battery has already been replaced (certainly NOT by my own standards, for sure!!! 👎), but the corroded resistors in the NMI/Reset circuitry had not been replaced, nor even cleaned from battery leakage corrosion!!!! ☹️☹️☹️ Meaning that the CPU is either constantly reset at start-up, or the reset generator fires up randomly because of the corrosion that prevents current to flow normally... 😔 . Clearly looks like some replacements are in order . #LexiconInc #LexiconM200 #Model200 #LexiconModel200 #DigitalReverberator #VintageDigitalReverb #EarlyDigital #Repair #VintageElectronicsRepair #VintageProAudioEquipment #StudiosSodasoundParis #SodasoundParis #SodasoundStudios #SodasoundStudiosParis #StudioPiscineATokyo #PiscineATokyo #TheGoodDoctorPrager #LeBonDocteurPrager https://www.instagram.com/p/Btsv5rXldYm/?utm_source=ig_tumblr_share&igshid=169xdsszj8loa
