8000W Rack amp
Fig2 Transistor ON/ONSEMI TO-3P NJW0302G/NJW0281G
Transistor TOSHIBA TO-220FP 2SA1837/2SC4793 A1837C4793
smaller transistors at the bottom of the picture.
A customer had this 8000W power rack that was fried, There was many components that were burnt,
This amp has 8 channels which have 2 identify boards 4 channels on each so if one channel goes you could still repair it with the other board if needed.
The components values are labeled on the silk so the major components that needed repairing was 100 ohm 1W resistors as seen in fig3. The ceramic resistors 0.25ohm 5Watts, Many power transistors they come in pairs of PNP and NPN so buy one of each for each channel. As seen in fig2
Here are some components
