This is a bare PCB of a tube amplifier. Each channel makes use of a single low noise tube 5670/6N3 at the input and proceeded by a power tube 6080/6AS7 to accomplish headphone power amplification. Each board consists of two channel thus one board can be used for stereo application. The schematic is shown below for reference. We provide detailed schematic ( with values and rating) to buyers by EMAIL. Supply voltage : rail voltage - AC 170 150mA; filament voltage - AC 6.3V 1A and 3.15Vx2 3A
We have a transformer "Transformer 170V 0.15A 6.3V 3.15Vx2 1A shielded for tube preamp headphone amp" that can be used with this board. The transformer can provide the 170V and 6.3V voltage ( for 5670 filament) to the board BUT not the 6080 filament. 6080 filament consumes 3A and best to be used with a separate filament transformer. Board Dimension : 170mm x 130mm. Board Thickness : 1.6mm
Copper thickness : 75um ( 4 times normal thickness) ; tin-plated surface.
