JJ GZ34 / 5AR4 Rectifier Vacuum Tube
Solid, reliable and cost effective, the JJ line of tubes create better than average tone and fail less frequently than many other types of tubes.

Great tubes! I've only had one fail shortly after installing... which is better than most tubes!

A fine, cost effective rectifier tube. Solid build and performance. I use these in customer tune-ups and rebuilds. Excellent option.

Truly one of the very best! Very solid performer and it is the only rectifier tube I use in any pro gear.

Awesome Rectifier. Slightly less sterile than the Sovtek equivalent.

Another great JJ tube. I use it in my amp and it sounds musical.
