      Outstanding value

      I bought this tube for a 5 watt tube amp that was whistling and sounded very low quality. After I replaced this EL84 along with their preamp 12ax7 tube the amp sounded very high quality . Yes it brought my amp back to life . So lush and powerful that it gives my $400.00 arch top jazz guitar world class tone. My amp sounds a lot more powerful I couldn't believe the transition. Now I'm a believer. My advice if your going to change your amps tubes change them all at once you won't be sorry. The tubes also shipped very fast . I would recommend to others.

    • Matched Tube Set From Viva Tubes

      JJ Electronics tubes are always reliable and economical. I run a small music electronics repair shop and JJ tubes are the standard replacement for individual and complete re-tubes.

    • Excellent for tube radios

      Excellent tube to replace NOS EL84 tubes in W. German radios from the 1950's. The JJ EL84 greatly reduces, or eliminates the problem with excessive bass on rock stations.
