Fostex HP-V8 vacuum tube headphone amplifier



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 balanced and unbalanced outputs

The proprietary powering system "Stabilized Tube-controlled Power Ciurcuit (ST-PC)" using KT88 tubes significantly reduces residual noise to achieve S/N ratio of 115dB

E88CC and 300B tubes are used as amplifier tubes and power tubes respectively

The base plate made of aluminum weighing 2kg and the OFC plate with teflon washers used for the power tubes mounting part completely eliminate vibration noise

High anti-vibration rubber feet isolate the chassis from the floor

Pure audio grade electric volume is used to completely eliminate the difference between L and R volumes

Custom-made electrolytic and film capacitors as well as Furutech AC inlet are adopted
