Groove Tubes GT-5AR4 Rectifier Tube
| Common to higher powered tube amps, like the later Fender Super Reverb amps and the Vox AC30 (or Matchless copies). It is the higher powered tube type rectifier in the marketplace. May be used to replace a 5U4 or 5Y3 and will give a faster, more dynamic tonal result. This rectifier has a rise time from 300-400 volts that is about 1/2 that of a 5U4, so they are very nice in amps such as the Mesa Rectifier series which use the 5U4. Great if you want a feel and response that is tighter than the stock rectifiers yet retain the feel and compression character of a vacuum rectifier over the solid state setting. |
