Hand-built Vacuum Tube Amplifiers and Preamplifiers for the the discriminating music lover.

Tube Preamps

This preamplifier replaces the Unlimited and fills the void with lots of upgrades including an ALPS remote volume control as stock. Optimized for the 12BH7 "super-tube", and can use 12AU7, 12AT7, 12AY7, and 12AX7. A solid-state MM phono stage can be added for $275.

  • 4 sets of line level inputs
  • 2 sets of stereo outputs
  • ALPS motorized volume control
  • ALPS rear output level control
  • Neutrik RCA jacks throughout

A robustly built stereo Single-Ended amplifier utilizing the KT88 Pentode in either Triode or Ultra-Linear mode producing up to 18 watts per channel.

  • JJ Blue Glass KT88 tubes (included)
  • JJ 12AT7 (included)
  • Triode/UL mode switchable
  • Audyn coupling capacitors
  • 4/8 ohm speaker output

This Stereo push-pull amplifier has been designed from the ground up to give the closest sound to a SET while using a push-pull output stage. Fewer and higher end components provide a transparent 3D soundstage and "meat on the bones" midrange that only SET designs are known for.

  • Class "A" Push-Pull operation
  • Cathode "Auto-Bias" requires no adjustments and prevents Bias failure issues
  • True Triode driver and phase splitters
  • Minimal signal path and less gain stages for increased transparency
  • Triode/UL mode (switchable)

Redesigned from the ground up! Now featuring an over-built outboard tube rectified and regulated power supply. Many updates to the circuit and componentry throughout to punch well above its weight class!

  • 1 Set of Stereo MM Phono inputs
  • 1 set of stereo line level outputs
  • true analog design
  • 100% point to point wired
  • (2) 12AX7's for RIAA correction and gain

Taking my KT88 120 single-ended Amplifier to the next level- this amplifier has many upgrades which combine to create a truly remarkable performer that provides more power and tube rolling options!

  • Single-ended design with switchable "Triode/UL" modes
  • Hybrid Tube/solid state rectifier system provides the stability of diodes with the smoothness of a tube rectifier
  • 6SN7 or 6SL7 driver stage in SRPP mode
  • EL34, KT88, KT120,KT150 compatibile
  • Audyn True Copper coupling capacitors

My vision of the most pure and transparent platform for the 300B single-ended amplifier. This amplifier delivers the wide midrange that the 300B is famous for, while keeping an extended airy high end and maintaining a solid, deep and extended low end.

  • 6SN7 input stage in SRPP mode
  • 6V6 driver stage in triode-strapped mode
  • 300B single ended output stage
  • Audyn True Copper foil coupling capacitors
  • Silver wire used in the signal path

A massive SET amplifier using either the 211 or 845 transmitter triodes, producing 25/35 watts respectively with graceful overload characteristics well over 40 watts. This ampliifer has been built to celecrate the true expression of these tubes in a no compromise design!

  • Input tubes: 6SN7 in SRPP mode
  • Driver tubes: EL34 in Triode mode
  • Power tubes: 211 or 845 transmitter tubes
  • Voltage regulator tubes: OC3
  • Damper diode tube: 6CG3

This completely redesigned push-pull amplifier is unlike any other available on the market. Able to utilize EL34, KT88, KT120 and KT150 tubes to produce anything from 20 watts of Triode-strapped sound to 80 watts of ultra-linear power- these mono blocks are robustly over-built and can handle virtually any speaker with ease!

  • Compatible with EL34, KT88, KT120 and KT150 power tubes
  • Compatible with 6SN7 or 6SL7 input tubes
  • 6V6GT Cathodyne phase-splitter
  • Power output: 20-80 watts per channel RMS (dependent on tube & mode)
  • Variable negative feedback/damping

A re-launch of my popular Special 6SN7 Line-Stage featuring many updates over the original while still maintaining the same sonic signature. An updated power supply section, Mogami shielded signal wire, TKD input control, Neutrik RCA connections and a solid hard-wood enclosure present some of the changes made to this preamplifier!

  • Tube rectified and regulated power supply
  • Audyn True Copper coupling capacitors
  • DC coupled input stage fed to a low impedance cathode follower
  • gold-plated ceramic tubes sockets
  • gold-plated Neutrik RCA jacks

A complete re-design of my 2A3 stereo amplifier utilizing an outboard power supply with all film capacitors, an updated driver stage featuring a 6SL7, ultra-low noise floor and many other updated components throughout  

  • 6SL7 SRPP driver stage
  • DC filaments/heaters used throughout
  • Film capacitors used throughout
  • Choke filtering for the power and driver stages
  • Toroidal filament transformers for the 2A3s

The Motherlode II is my flagship line-stage preamplifier! Delivering an organic, yet extremely fast and transparent rendition of the audio signal using boutique parts throughout. Both 6SN7s and 6SL7s can be used in this model.

  • 6SN7 or 6SL7 compatible
  • Exclusive film capacitor power supply
  • Dual chokes
  • All toroidal transformers
  • Tube rectified using a 5U4. 5U4G or 5U4GB
