1960-1962 Farfisa developed the first generation Cordovox vacuum tube accordion, the CG-2 and CG-3, which used tubes in a suitcase-sized tone module to generate sound. The Cordovox CG is the Tube Amplifier and Tone Generator.

The Cordovox CG consists of 2 parts, an amplifier and a tone generator. It has 66 tubes of which 8 are for the preamplifier (12AU7's and 12AX7's) and 58 for producing tonal chords (6X8's and 6FH8's). All inputs and controls are housed at the top of the tone generator. The amplifier is housed in an identical sized cabinet and has two 12 inch speakers and the power amplifier. 
Tubes for the power amlifier are one 12AX7 and two 7591's.
