Abstract

A power supply for use with a musical amplifier includes two user-selectable rectifiers for variously enhancing sound generated by a musical instrument such as a guitar, or by recorded musical material which in either case consists of electrical signals applied to a vacuum tube amplifying apparatus. The first of two rectifiers comprises one or more thermionic vacuum tube devices, depending upon power needs, while the second rectifier is comprised of solid-state silicon diodes. A switch circuit enables the user to select which of the two rectifier devices is better suited to the contemporaneous use of the amplifier.

Claims

1. A dual rectifier power supply for use with musical amplifiers comprising

input means for providing a source a AC power,

a first, solid state rectifying means for converting AC power to rectified DC power and having an output,

a second, vacuum thermionic rectifying means for converting AC power to rectified DC power and having an output,

switch means accessible to the user of the power supply for selectively connecting the input means either to the first rectifying means or to the second rectifying means,

output means connected to the outputs of the first and second rectifying means for providing a source of rectified DC power in a manner adapted to be connected to a musical amplifier.

2. A dual rectifier power supply for use with musical amplifiers comprising

input means for providing a source a AC power,

a first, solid state rectifying means connected to the input means for converting AC power to rectified DC power and having an output,

a second, vacuum thermionic rectifying means connected to the input means for converting AC power to rectified DC power and having an output,

switch means accessible to the user of the power supply for selectively connecting either to output of the first rectifying means or to output of the second rectifying means, and

output means connected to the switch means for providing a source of rectified DC power in a manner adapted to be connected to a musical amplifier.
