     Parameter List

     Features

  •  15W All-Tube Amp Head, 1W/15W Power Switching
      Meets different volume requirements for home practice,
      recording,  and small performances. Authentic tube overdrive
      can be achieved even at low volume.
  •  12AX7 + Dual EL84 Classic Tube Combination
      Delivers warm, delicate, and highly dynamic British-style tone,
      suitable for both clean and mid-to-high gain performance.
  •  OriPure Handmade Push-Pull Output Transformer
      Each winding layer uses paper insulation, effectively reducing
      dielectric constant (Dielectric Constant), minimizing stray
      capacitance (Stray Capacitance), and increasing resonant
      frequency (Resonant Frequency), resulting in more delicate,
      transparent, and dynamically responsive high frequencies.
      High-grade grain-oriented cold-rolled silicon steel sheets
      (Oriented cold-rolled silicon steel sheet) are used to increase
      inductance (Inductance), delivering full, solid, and punchy low
      frequencies. Push-pull output design provides stable power
      output, clean response, and natural gritty distortion suitable
      for more musical styles.
  •  Aluminum Alloy Chassis, Sturdy, Durable, and Excellent
      Heat Dissipation
      The aluminum alloy chassis combines mechanical strength
      with efficient heat dissipation, ensuring stable and reliable
      long-term operation.
  •  8Ω / 16Ω Dual Impedance Output
      Compatible with most 1×10, 1×12, 2×12, and 4×12 cabinets on
      the market, allowing flexible amplifier system configuration.

     OriPure OA-H15 is bold and highly penetrating, featuring the
     signature gritty (Grit) overdrive brought by the classical
     push-pull output structure. Powered by a 12AX7 and dual
     EL84 tubes under the boost of OriPure’s pure handmade
     output transformer, it delivers warm yet wild electric
     guitar tone. 
     Whether your music burns with the soul of British rock or
     roars with the grit storm of hard rock, it drives your guitar
     tone to the peak with real, raw, and untamed tube character!

  •  Clean
     At low GAIN settings, the tone is transparent and warm, with
     rounded highs and naturally full midrange, perfect for arpeggios,
     fingerstyle, and blues clean tones.
  •  Crunch
     At mid GAIN settings, the tone begins to break up. The edges are
     soft with fine grain, and a clear sense of grit appears while
     maintaining good chord clarity. The dynamic response is excellent,
     easily controlled by picking strength—light picking stays close
     to clean, while hard picking brings strong crunch.
  •  Overdrive
     As the GAIN increases, the amp enters a smooth and natural tube
     overdrive range. The push-pull output structure makes
     mid-to-high gain tones thick and powerful, with tight low end
     and strong midrange penetration, ideal for rock and hard rock
     solos and rhythm playing.


     Frequency Response:
     • Low: Solid, elastic, not muddy
     • Mid: Prominent, strong penetration, rich “tube character”
     • High: Transparent and delicate, no harshness


     Suitable Styles:
     British Rock / Britpop • Classic Rock • Hard Rock • Blues • Funk •
     Jazz Fusion • Pop • Indie / Alternative

     Application Scenarios:
     • Home practice, the 1W power mode is especially suitable for night
       practice and home use without disturbing others while retaining
       real tube dynamics.
     • Home recording / studio recording
     • Small rehearsal rooms
     • Café and bar performances
     • Teaching and training use

     Installation Instructions

     • Connecting the speaker cabinet:
       Use a 6.35mm speaker cable to connect the 8Ω or 16Ω output
       of the OA-H15 to a cabinet with corresponding impedance.
     • Connecting power:
       Select the 110V or 220V voltage setting according to your region
       and plug in the matching power plug.
     • Connecting the guitar:
       Use a standard 6.35mm instrument cable to connect the electric
       guitar to the front panel input jack.
     • Power-on procedure:
       1. First set Standby to OFF (standby mode).
       2. Turn on the power switch and allow the tubes to warm up
           for approximately 30–60 seconds.
       3. Switch Standby to ON to enter normal operation.
