Detailed Product Description

Pre-11 tube preamplifier
Pure handwork fabricate, unique appearance, very select material, adopt vacuum tube amplifier, for special purpose spare parts
Machine feature:
Adopts two sets an independent power supply the electron circuit, use 5ar4 rectifications, adopt electron steady voltage circuit, use 6j8p,6n12p, zener diodes component, this can ensure foreign voltage have change sometimes, always keep this machine DC supply not change, make voice more perfect euphony
This product uses two piece 6n8p vacuum tube, have multiple and series two way output. Multiple is anode output, series is cathode output. Two kinds of output means, can supply audiophile choice
Added two piece irt-730 mosfet, possess output stability and dynamic big power feature.
