- Output: binding posts
- Power transformer: 0.35mm SiFe lamination, properly aligned, multiple vacuum impregnated for durability and noise free operation.
- Chassis - steel (or stainless steel for some versions), double layered design, no-minimal surface screws.
- Output transformer - heart of a tube amplifier, for high end edition, comes with transformer case with potting compounding for shielding, protection and look.
- Power supply - full wave vacuum tube rectification (315V-0-315V), with imported SiFe cores as power and choke (CLC power supply), with imported Philips or Rubycon (may vary) power supply capacitors.
- Amplification - adopt and improve on classic Japanese design, with 2 stages of Triode common cathode amplification stages, capable of high voltage swings and high driving current.
- Alps volume control.
- Power transformers - using EI 96 - 60mm stack huge cores. capable of 200W power, with imported 0.35mm lamination high Gauss SiFe. Magnet wires are high grade OFC from big factories, with multiple tight layering. Have extremely low loss (low no load current), no rattling/hum/vibrations. Warranty for 2 years.
- Output transformer - multiple layered precision wined, using made in Japan ultra thin insulation (0.06mm, 2000V insulation strength), with classic series-input, and parallel-output characteristics, achieving output transformer requirements of high primary inductance and low stray inductance design. 2 versions - EI66-36 and EI76-40.
- Capacitors - imported electrolytic capacitors as power supply capacitors (Philips/BC, Elna, Rubycon and etc); uses audio grade coupling capacitors.
