Synthchaser #108 – Vintage Minimoog Repair & Tour Inside

Today we have a tour around the inside of a vintage Moog Minimoog Model D with a damaged and dangerously miswired power cord. I show you how to open up the synthesizer, what’s inside, and how to change the power cord and power light.

Power lamps are available here:

Synthchaser #107 – Homemade LM3900 Norton Op Amp Tester

In this short video, I explain what an op amp is and how a Norton Op Amp is different, and then show a little test fixture I made to test these specialized IC Chips that I run into frequently while repairing vintage synthesizers.

    On the bench today is this Roland Jupiter 4 and its little brother, the Roland Promars. But it's such a nice day they decided to come out for a little sunshine and fresh air. Notable Jupiter 4 users include Vince Clarke who used the JP-4 on Depeche Mode "Speak & Spell" and Yazoo's "Upstairs at Eric's"#jupiter4 #Roland #depechemode #vintagesynth #synthrepair ...

    Two Vintage Oberheim OB-8s! One just got some much-needed love and has been picked up by The Music Company where it’s now available for people to play. Always nice to get these classics back in action!Once I service the other OB-8, it’ll be available for sale. If you’re interested in owning a nice OB-8, hit me up.#OberheimOB8 #Oberheim #VintageSynth #SynthRepair #AnalogSynthesizer ...
