This is a bare board of a headphone amplifier that features 6DJ8 tube input and source follower output by a MOSFET in pure class A mode. The whole circuit has no global NFB which is very beneficial to sound reproduction. Sonically the amplifier has a relaxed, open and neutral sound. The class A output stage allows the amplifier to drive any impedance with ease. PCB dimension : 135mm x 98mm.Board thickness : 1.6mm.
Copper thickness : 70um - 4 times of normal board copper thickness ! We provide schematic and part list to buyers by EMAIL.
