Tung-Sol GZ34 / 5AR4 New Production Rectifier Vacuum Tube
The Tung-Sol 5AR4 is an ultra efficient indirectly heated dual diode, full-wave vacuum rectifier. Providing a mere 10V drop in B+ (plate voltage) at full current demand, this rectifier insures a strong, dynamic response to your sound. An excellent and reliable choice, the Tung-Sol 5AR4 comes with a classic brown base, tandem supported getter cup, dual mica spacers and full 30mm length internal plate structures. This tube is an excellent replacement of any GZ34 and 5AR4 rectifier tube.

Excellent tube. I've been using it in my High Power Fender clone I built. 4 tube matched set all biased correctly and easily.

Solid go to 5ar4. Nice headroom and has that punch like the amp is never starving for more power.

Excellent tube. I've been using it for a couple weeks and it has been there with no failure. It brought my Vox AC-30 CC2 back to life. It also helped with the tone a little bit.

Got this on sale for my Dynaco ST70 amp. I've run it (for hours per day at 360VAC per side) for a comple weeks now and so far so good.
