An amateur fixes what professionals broke - OSCar Part 5

The OSCar arrived back from repairs, more broken than it was before. What damage has been done? Can I fix it? Of course I can, I have a new desoldering gun! The Oxford Synthesizer Company OSCar is a nearly mythical monosynth used by Ultravox, Jean-Michel Jarre and many more, perhaps most famously it provided the synth bass line in "Do They Know It's Christmas?" OSC manufactured less than a thousand of these, making them as rare as they are weird. This rarity, together with the unusual design, questionable build quality and the company's brief life means it is sometimes called "The DeLorean of Synths". Repairing this one has taught me a lot about the OSCar, if you have one in need of repairs, do not hesitate to contact me for advice and help. It is NOT easy to repair, you need an expert.
