The JJ Electronic 6CA7 is a true to form reproduction of a classic tube that will work in most EL34 amps. The 6CA7 is often considered the American cousin to the British EL34. Sonically, this tube is closer to a 6L6 than an EL34 but without the sometimes harsh high end of the 6L6. The JJ 6CA7 offers warm highs with punchy articulate mids and tight lows. Wielding even more power than a KT77, this tube is a great choice for people looking for a change in their EL34 amp’s tone or want to push their levels that much further.
