Groove Tubes

collapse expand iconDescription

The most common rectifier tube used in higher powered amps which use a rectifier, such as Fender 40-watt 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 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. They 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.

    Groove tubes are a good value, and are very dependable. I'm glad that Guitar Center still stocks them.

    This rectifier worked fine with no rattling. I am not familiar with using newer GT tubes and only needed this to throw in a backup amp we were getting rid of.

    Good product. Not made in the U.S.A. like I was hoping, but will do the trick for now. Good deal for the money though.
