TA3020 based unassembled KIT amplifier. Output power: 2x300W on 4R impedance or 2x155W on 8R impedance at +-56V supply voltage with the standard MOS-FET's STW34NB20 or 2x385W on 4R impedance or 2x200W on 8R impedance at +-60V supply voltage with improved IRPF4321 MOS-FET's. The board size is 100x100mm and the transistors can be mounted either horizontally on the base-plate of the amplifier or vertically on the heatsinks which are available as option. The board uses only high-quality THD components, no SMD components at all, giving the chance to be built even for those less familiar with SMD soldering techniques. The current kit is sold in unassembled form, as PCB board, all the components and schematic with assembly instructions. The kit contains all the parts necessary to build an amplifier module as the one seen in the picture. Upgrade components and heatsinks are available and a dedicated power supply is under design. The assembled and tested version can be ordered as well selecting the option below. WARNING !!! Since this Kit is unassembled, it requires proper tools and knowledge to be able to build a fully working amplifier. The levels of voltages required for operating this amplifier KIT are hazardous and extreme care should be taken when testing and adjusting the kit. Thus it is only recommended for experienced users, NOT for beginners.
