Fostex HP-V8 300B Vacuum Tube Headphone Amplifier

Fostex

Model HP-V8 is the high-end stand alone vacuum tube amplifier dedicatedly designed for headphones using the legendary 300B for power tubes for the first time in the industry on headphone amplifier.

  • The Signal to Noise ratio as good as 115dB achieved by the Fostex proprietary ST-PC technology as well as thorough noise reduction countermeasures reveals the authentic power of the tubes. The proprietary powering system “Stabilized Tube-controlled Power Circuits (ST-PC) using KT88 tubes significantly reduces residual noise to achieve S/N of 115dB. E88CC and 300B tubes are used as amplifier tubes and power tubes respectively. The power section consists of toroidal power transformers, heater transformers and a choke transformer made by Bando Electronics.

  • Output transformers are custom-made by Hashimoto Electric complying with balance and unbalanced outputs. The base plate made of aluminum weighing 2kg and the OFC (Oxygen Free Copper) plate with Teflon washers used for the power tube socket to minimize vibration noise. High anti-vibration rubber feet isolate the chassis from the floor. Pure audio grade electronic volume is used to eliminate the gang errors between L and R volumes. Custom-made electrolytic and film capacitors are adopted The audio grade AC Inlet is made by Furutech
