Assuming the jack cable is plugged in (believe me it happens more than you’d think!), this could be one of several reasons, most of which are very simple fixes: The battery is dead Hohner Clavinet’s use a 9V Battery to power the internal pre-amp. The most common reason it won’t power on is because the […]

Vintage instruments can often be noisy. But there’s something about a Hohner Clavinet that when it starts to become noisy, it really goes for it. Whether it’s hum or a type of static, here are a few things that you can take a look at: Electrical interference: Hohner Clavinets are very sensitive to noise interference […]

In electric pianos, a pickup is an electronic device that captures the vibration of the tine, reed, or string and converts it to an electrical signal. There are two main types of pickup that are used in electric piano instruments: Electromagnetic Pickups: Electromagnetic pickups use a magnet and coil arrangement where a magnet is surrounded […]

(See Power Transistor for this specific transistor type) A transistor is an electronic component found inside most electronics. It is a type of semiconductor, and a key component in amplifying a signal in a circuit. Depending on the type, the way a transistor works is to act as an amplifier or switch – where signal […]

Capacitors are components used in an electronic circuits that have multiple functions including storing charge, regulating voltage, filtering frequencies, coupling and decoupling, creating oscillating circuits and protecting circuits. In the very simplest sense they store and release energy like a battery, though this energy is utilised in many more different ways. In electric pianos they […]

An electrolytic capacitor is a polarised type of capacitor that is inside many electronic circuits, including Rhodes preamps and Wurlitzer amplifiers. The reason they are used is because they can store a much higher charge, or capacitance, then regular film or ceramic capacitors. In audio circuits like a Wurlitzer or Rhodes amplifier this is done […]
