CORDOVOX AMP AND TONEGENERATOR GENERATOR

One of the unusual remaining features of the original Cordovox circuit is the negative feedback loop that returns to the second stage preamp tube instead of the phase inverter as is typical. Following good practice, such building blocks can, of course, be adapted to taste. The result is an impressive sounding amp with the solidly vintage character reminiscent of 7591 amps, such as the early Ampegs and Premiers.ĭuring the process of converting the Cordovox Accordion Amp, I tried to retain as much of the intent of the original circuit as practical while incorporating many of the classic elements of tube amp design. Although the amp truly sounds amazing, I don’t consider this work to be perfect or final.
