Abstract
An Electronic bass register musical instrument tube preamplifier includes an in line signal pre-amplification device in a Class A audio amplifier configuration. The pre-amplification device includes one or more modern thin film capacitors coupled to the output of the preamplifier circuit from the anode of half of a dual triode 12AX7 electron tube and one or more “paper in oil” capacitors. The one or more “paper in oil” capacitors are coupled to bypass and decouple to ground at the anode of half of the dual triode 12AX7 electron tube.
Claims8
An electronic bass register musical instrument tube preamplifier, comprising:
- an in line pre-amplification device in a Class A audio amplifier configuration, the in line pre-amplification device comprising:
- one or more modern thin film capacitors coupled to the output of the preamplifier circuit from the anode of half of a dual triode 12AX7 electron tube;
- and
- one or more “paper in oil” capacitors, wherein the one or more “paper in oil” capacitors are coupled to bypass and decouple to ground at the anode of half of the dual triode 12AX7 electron tube,
- wherein the one or more “paper in oil” capacitors are coupled to ground by way of one or more conductors and in parallel with one or more resistors,
- wherein the combination of the one or more modern thin film capacitors coupled to the output and the one or more “paper in oil” capacitors bypassing and decoupling to ground is configured to richen the tone of bass register musical instrument electronic signals, and
- wherein the in line pre-amplification device is configured to richen the tone of an electric bass guitar in at least the lower octave and a half of the electric bass guitar.
