It’s incredible that some electronic components are so rare. We can’t reach a post-scarcity economic utopia (where we only trade services) as long as specific resistors are so hard to find. I saw a dozen of Yamaha Electone organs for sale 10€ each at a local recycling center. Each device has components inside them which cost more. I should start a component upcycling business. Some info on the Electone organ chips is available online.
Tried my best to get the WSG working again. Sanded the paint away from the case (under the potentiometers) to create a stable ground connection, added a ground wire from the “-” power lead to the case and replaced the audio jack. Results: Only sound A Osc.2 is working. Bought new components for a second unit. I’m determined to build a working noise box.
