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.

  • Dynaco Rectifier

    As reviewed by Ronald Braun on 1/2/2012

    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.

  • Perfect for Dynaco Stereo-70 Amplifier

    As reviewed by Eric on 6/15/2011

    The 5AR4 is the factory-specified rectifier tube for an ST-70 amplifier, and the Sovtek is considered to be a good brand for this tube. I bought this one a few weeks ago and it works perfectly and my amp sounds great. It's nice because it doesn't slam your power tubes with immediate power, but ramps up the power gradually as it warms up over 20 seconds or so.

  • Best 5AR4 value out there

    As reviewed by Dynaco on 4/25/2011

    The Sovtek 5AR4 tube is a rugged tube that can be used in many tube amplifier applications. I personally use them on my Dynaco ST-70, Dynaco Mark III and Dynaco Mark IV tube amplifiers. They are well made and stand up well to daily use.
