Abstract
A vacuum tube amplification unit for use with electric instruments that allows for reduced or eliminated signal loss before the electrical signal of the instrument is amplified. The vacuum tube amplification unit includes an amplifier cartridge having an amplification circuit. The amplification cartridge is attached to and electrically connected to an instrument through a cartridge receiver. A pre-amp assembly of the amplification circuit provides a first stage of amplification, while an at least one vacuum tube provides a second stage of amplification. A power supply provides current to amplify the electrical signal of the instrument and a gain control allows for adjusting the magnitude of amplification. The amplification circuit may further include an integrated speaker, a signal converter, a transmitter, and a device terminal. Additionally, the amplifier cartridge may further include a device dock for attaching an electronic device.
