Yeah, I’ve spent a lot of hours coaxing those old beasts back to life. The oscillators get fine‑tuned with a good set of screwdrivers and a decent multimeter. A laser‑grade rig is nice for a showpiece, but for a working unit I stick to a solid grounding, a reliable power supply, and a bit of patience. Once the voltage is stable and the filters are calibrated, it sings like a well‑lubed machine. No need for fancy optics if the core components are in line.

You’re right, stray millivolts can make a decent synth feel like a jazz solo gone rogue. Tighten those filters, check for floating grounds, and if it still moans, I’ll put it through a quick voltage sweep and maybe replace a few resistors. Don’t worry, I’ll keep the machine in line and only ask for a quick revamp if it starts behaving like a teenager.
