Description: Hybrid (tube for preamplification, transistors for amplification) high end headphone amplifier. Top right is the power input with a noise filter, below it a toroidal transformer and to the bottom the RCA plugs. The tube on the left part of the PCB is a double triode (one for each channel) for the preamplification stage. Above and below it are two separate volume controls. Bottom left is a 6.3mm stereo plug. In the middle of the board is the input from the RCA plugs and right next to it are the transistors used for the last stage of amplification.
