The 5AR4 is Sovtek's version of a common rectifier tube used in rectifier-equipped high powered amps such as Fender 40W and Vox AC-30 amplifiers. Common to higher powered tube amps, like the later Fender Super Reverb amps and the Vox AC30 (or Matchless copies). May be used to replace a 5U4 or 5Y3 tube and will give a faster more dynamic tonal result. The Sovtek 5AR4 rectifier has a rise time from 300-400 volts that is about 1/2 that of a 5U4 tube. Sovtek 5AR4s work nicely in amps such as the Mesa Rectifier series which use the 5U4. Great if you want a feel and response that is tighter than stock rectifiers yet you want to retain the feel and compression character of a vacuum rectifier over the solid-state setting.

Needed a good 5AR4 for my Welborne ST70 Mod. These Sovtecs cost less than the Sino brown base. The service was great, received them right away. I always order two tubes for a particular use as a back up, you never know when a surge may take one out, especially a rectifier. I'll be back... Doug
I really haven't had it long enough to see. Time will tell how reliable this tube is. This is installed in a Dynaco ST-70. I'm hopeful that it lasts longer then the "JJ" tube that was in there for about 1 year and went up like a flash bulb. So far, last 2 weeks it's been working great. Nice steady B+ voltage.
I put this bad boy in my Fender Super Reverb and WOW! Just the best bang for buck out there!
