Vacuum Tube - E83CC Frame Grid, JJ Electronics
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.

Great sounding tube! Much better than the JJ ECC83S! Very open sounding and more dynamic. A bit more gain as well. Reliability is a question as I just put these in. Hope for the best on that part.
Bought 4, one failed after 45 hours/5 days of usage. It was replaced under warranty. Thank you.
I cannot tell a significant sound difference from the JJ ECC83 standard 12AX7 tube @ less than half the price!
Expensive, but worth it. I replaced a pair of Chinese 12AX7B’s in my Quicksilver Headphone Amp with a pair of these....a great decision....significantly better mid-range and deeper/tighter bass.
Very "well rounded" pre amp tube. Low microphonics. Great in HiFi applications. Works well in guitar amps in the V1 position as a 7025 replacement. Pretty good bang for the buck. JJ is really putting out some great sounding tubes at very reasonable prices.
Great business to work with, had everything I needed, prices are great, and delivery was fast.
