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

    I need your opinion of which synth do my next video on.  Choices are the Roland System 700, Yamaha PSR-520, or Casio SK-1.  Your input would be appreciated.#vintagesynth #modularsynth #analogsynth #roland #rolandsystem700 ... See MoreSee Less
