Platinum Matched, selected tubes
Nice mids, sparkling highs and solid bottom end characterize this tube

The JJ GZ34 / 5AR4 is another affordable replacement rectifier tube for both guitar and hi-fi amplifiers.

Selected tubes for low noise and low microphonics. Balanced, matched triodes. 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.

The JJ 5Y3 S is a solid, reliable, long-life rectifier tube.

The JJ EL 6550 is a very reliable tube with a large detailed sound. Highly recommended for Ampeg and others.

A fresh breath of air characterizes the JJ 6CA7 tube. When looking for a balanced sound, a top end that is never harsh or biting and a nice, round bottom end then look no further. The JJ 6CA7 has more beef then the EL34 but retains clarity and freshness all around.

The JJ EL 844 has nice mids, sparkling highs and solid bottom end characterize this tube. Reduced output and earlier breakup compared to a JJ EL84 tube. Drop-in replacement for most cathode and fixed biased EL84 amps.

Another awesome release by JJ Tesla, totally living up to the hype. JJ created a perfectly musically transparent KT66.

The great KT77 is back, reissued by JJ Tesla.

The bass is unique in that it compresses the very bottom end. This provides incredible bass response without ever losing control. Overall a great tube for orchestral, opera, and jazz music.
