Here we have a killer HM18. EL 84's and a GZ34 rectifier, a 1x12 Tone Speak special design Tyler 50 watt 8 ohm speaker. The HM18 has Volume, Tone and a MV. This is a hand made and handwired amp based off of the early Matchless Spitfire/Vox AC-15 style amps. It’s best compared to the power section of a Vox or Matchless paired with the preamp from an 18-watt Marshall. A great studio and road amp built to last a lifetime. Dimensions: 18.5"x 18"x 10.5" just over 37 lbs.
