Sovtek 5Ar4 Rectifier Tube #3820fx

Sovtek 5Ar4 Rectifier TubeThe 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.

This Groove Tubes rectifier may be used in amps such as the Matchless DC-30 series and similar amps when you want more compression, less attack, and to lower the voltages in these amps. The GT-5Y3 rectifier gives a nice feel to these amps with a much slower rise time than the 5AR4 or the 5U4, with a great feel. The Groove Tubes GT-5Y3 rectifier will also let amps such as the Matchless distort at a lower volume to make them suitable for smaller venues and to record sweetly at lower settings.Country of origin: Russia Country of origin: Russia

Bugera 5881-4 Pack Matched Power Amp Tubes #1677pq

Bugera 5881-4 Pack Matched Power Amp TubesThe Bugera 5881-4 Pack Power Amp Tubes are subject to rigorous quality tests such as a 48-hour burn-in test and their vibration table test. 5881’s are also more commonly referred to as 6L6 tubes. The 6L6 and 5881’s are the most popular tubes currently used in guitar amps. The tonal qualities of the 6L6 and 5881 emphasize lows and highs with a somewhat relaxed (some will call it scooped) midrange, and is equally at home pushing out sparkling and chiming cleans, swampy surf sounds, or high-gain dropped-D chugging. Their versatility has led many amplifiers to use these tubes as the backbone of their channel-switching amp designs, as they tend to sound great when being fed varying amounts of gain from clean, to crunch, to CRUSH. The headroom capabilities are great for high-power clean setups, or to keep the low end robust in high-gain rhythm guitar scenarios.
