JJ 5751 Preamp Tube
The JJ 5751 preamp tube can be used in most 12AX7 circuits to achieve more headroom.
The JJ 5751 was designed as a “ruggedised” high mu, dual triode tube with similar specifications to the 12AX7. With 30% reduced gain, the 5751 is a fantastic way to tame a distortion stage and tone shape an amp. They and are often used to quiet down guitar amps that have too much gain.
These “short plate” 5751’s utilise a “short plate” design and the tubes have great compression and harmonic complexity, they are perfectly suited for creating articulate mid-range and warmer high end response.
