This is an assembled board of a singled-ended(SE) output tube stereo amplifier. Each channel makes use of a single low noise tube 12AX7/6N11/6H1 at the input and proceeded by a power tube( 6L6/EL34/KT88) to accomplish power amplification. The output power is around 3Wrms with 6L6 and 8Wrms with KT-88. The board contains all the components, EXCEPT the three tubes. The board contains high quality components such as Dale non-magnetic resistors and 1% metal film resistors. Power transformers and output transformers are NOT INCLUDED. We provide schematic to buyers of this board by EMAIL. We do air shipping worldwide at US$8.50.
