The first electronic amplification of sound was done with Vacuum Tubes. We have pre-amp, power and rectifier vacuum tubes among other types in New Old Stock from the golden era of American & European manufacturing as well as current production tubes from today.
Vacuum Tube - E83CC Frame Grid, JJ Electronics
Alternative to the 12AX7 or ECC83. The JJ Electronic E83CC is a high quality dual triode that rivals the NOS version of this tube. The E83CC was originally designed as an audio specific dual triode with very low noise and microphonics. The JJ E83CC stays true to the original design with the signature thick frame grid and boxed plate. The rigid frame allows for tighter tolerances and closer construction which results in lower noise and increased stability. The JJ Electronic E83CC is a great choice for high fidelity amplifiers as well as guitar amps and studio equipment. The E83CC has the same pinout and amplification factor as a standard 12AX7 and can be used in any 12AX7 or ECC83 position. Guitarist Description: This frame grid tube has an incredibly rich yet balanced tone. The E83CC works well for clean sounds but also breaks up with a satisfying warmth and plenty of articulation.
