This Farfisa Mini-Compact organ came into the shop completely dead ... No lights, no sound.

A burned-out pilot lamp and a bad output cable explained the keyboard's quietus.

But once those problems were fixed, playing revealed that C# notes were fluttering between octaves.

This is a sign of problems in the C# divider circuits.

We pulled out the Mini-Compact chassis and replaced a handful of old, germanium transistors.
