JJ Electronic preamp audio tubes such as ECC83-S, ECC82-S, ECC803S, ECC802S, and more, are available with standard pins or gold plated pins. The JJ power output tubes like 6L6-GC, E34L/EL34, 6V6-S, EL84, 6CA7, KT88, KT77, KT66, 300B, 7027A, and 7591-S are all great performers. JJ has also produced a few unique vacuum tube variants not produced elsewhere - specifically the EL509S, ECC99, and EL844 tubes.
