Used In: JCM 800s** and JMPs** (general replacement)

This would work well in a 6L6 / EL34 and will work OK in 2 tube 50 Watt or even say 4 EL84's for like a Heavy Duty Matchless or Vox 30. This may be a little more in line with 6L6 around 4000-4100 but will work with EL34's 3500 - 3600 kind of between the two covering both at 3900.
