JJ 5751 is a drop-in replacement for any 12AX7 / ECC83 tube
5751 can be used in most 12AX7 circuits to achieve more headroom. It has a lower gain than the standard 12AX7. Good to rope the gain of a high gain amplifier.
The JJ 5751 is a drop-in replacement for any 12AX7 / ECC83 tube. It is a dependable, high mu double triode with reduced gain and clearer, more articulated tone than a higher gain ECC83. Full and chimey mids, a tight bottom end and greatly reduced hum and noise characterize this tube. Highly recommended.
