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.

    For sale at synthchaser.com I've got an MTI Auto Orchestra AO-1. A rare and quirky all in one synthesizer and rhythm machine, with an 808-ish sounding drum and rhythm section, a bass synthesizer, string synthesizer and chord synthesizer. With its warm analog tone and retro character, it’s a unique all-in-one piece that brings instant vintage vibe and inspiration to any studio or collection.#vintagesynth #synthesizer #808 #drummachine #analogsynthesizer ...

    Finding needles in a haystack! Repairing an ARP Omni 2 that was playing 2 notes with one key and found this scratched trace microscopically bridging to its neighbor. Before that, tracked down a problem of the upper 29 keys not working to this inconspicuous cut trace (why it was cut and by who will forever be a mystery).#arpomni2 #synthrepair #vintagesynth #ARP #Synthesizer ...
