This is the bare PCB of a pure class A MOSFET amplifier, output power 100W at 8 ohms loading. The design is reference to A-2 The design takes minimalist approach, single-ended configuration for warm and musical sound. The board can be configured with 5 pairs of output transistors per channel like A-2, or with three pairs of output transistors like A-5 per user's power output requirement. This is a kit of bare PCB that can form a stereo amplifier. Two PCBs are contained in this selling item. PCB dimension : 343mm x 62mm. PCB thickness : 2mm, 2 oz ( 75um thickness copper) deposition which is FOUR times normal process of copper thickness.Gold plated surface. We provide schematic and part list to the buyers by EMAIL( to be attached with shipment notice).We do air shipping worldwide at US$8.00. |
