JJ KT77JJ KT77The JJ KT77 is an alternative to the common EL34 tube.
From our review: "Overall a nice balance of tone in bass, midrange and treble. The breakup is earlier than a 6L6 with more compression but not as compressed as the EL34. If you have a Marshall amp and find EL34’s too compressed and 6550’s too crunchy the JJ KT77 may be just the ticket."

RFT EL34RFT EL34The RFT EL34 tube is an outstanding value for a NOS EL34 tube. From our review: "These tubes are extremely warm sounding and if you have one of those amps that sound thin at lower volume levels, these should take care of that problem in short order. Midrange response seemed slightly skewed toward the bass side. This is no doubt where the extra warmth is coming from. The high end was smooth and clear without a trace of harshness."

Mesa Boogie offers this tube with their part number STR450.
