JJ ECC803s / Hi-Performance 12AX7 Preamp Vacuum Tube
The JJ ECC803s is a hi-performance 12AX7 that has a spiral wound filament to reduce noise and hum. The construction is different from the JJ ECC83 in that the plates are more conventional, but have a special heat dissipating fin that serves to improve efficiency and gain. The plates of the tube are also “over-sized” (longer) as compared to most standard 12AX7 tubes. This over sized plate structure improves details in the bass and low mid-range responses. If you want that great JJ tone in a hi-performance package, then these are for you. Compare with other tubes here.

However, with 30% reduced gain, the 5751 is a fantastic way to tame a distortion stage and tone shape an amp.
