Carl Verheyen and the Breaker 2x12    



  • Model #: 6LP
  • 45 Watts
  • Class AB
  • Fix Bias

Hand Wiring

  • Each Breaker amp is hand wired on high grade epoxy turret board insuring durability, stability and road worthiness
  • solid cloth covered wire like the original (as opposed to stranded plastic coated wire) -- a must for a vintage, sweet tone
  • Outstanding wiring techniques for a neat and clean look, less hum and less noise


Dimensions: 18 1/2 " (H) x 28" (W) x 10 1/2" (D)

  • Finger jointed solid pine
  • Strong, durable
  • Great natural resonance
  • Tolex


  • High Grade Stainless steel, less magnetic interferences (LESS HUM, LESS NOISE) and rust proof
  • High grade Stainless Steel screws
  • High grade Stainless Steel aircraft locking nuts for less vibration
  • Industrial quality glass filled tube sockets, no rattling noise like NOS style counterparts. Tubes can be inserted and removed thousand of times
  • All grounds are done with 18 gauge stranded wire, translating in LESS HUM, LESS NOISE


  • High quality Carbon composition, important ones are usually NOS Allen Bradley or Riken Ohm (Made in Japan) high precision, gold plated copper leads.
  • Each resistor individually measured before wiring to insure exacting tolerances
  • Low noise
  • High temperature tolerance
  • Extreme reliability
  • Warm sound


  • High quality Copper Foil or Solen Fast (made in France) coupling & decoupling caps
  • Sprague Electrolytic Sprague or  CDE (made in USA) for filtering caps
  • highest quality and durability
  • Key ingredient to the vintage tone - modern polypropylene film caps sound too bright
  • All caps are formed slowly with a variac for stability and less noise

Power Transformers (by Mercury Magnetics in California)

  • Highest quality transformers made by Mercury Magnetics
  • Hand wound, paper interleaved
  • Period correct voltages -- no cold, harsh, high plate voltages
  • Center tapped filament -- no heater hum
  • Available in 220V / 240 V / 100 V

Output Transformers (by Mercury Magnetics in California)

  • Highest quality transformers made by Mercury Magnetics
  • Manufactured using the actual Triad engineering data
  • Hand wound, paper interleaved on paper bobbins
  • High efficiency
  • Rich harmonics - astounding tone
  • Built to last forever
  • Tremendous bottom end, shimmering highs, a lot of headroom


  • Every component (resistor, capacitor, pots, etc.) is tested before installation
  • Every soldered connection is tested
  • Voltage checkpoints are verified throughout the circuit
  • I test every amplifier for a substantial amount of time (sometimes it's hard to stop playing...) and listen for potential rattling, vibrations sweeping frequencies with an audio signal generator.
