Empty board size: 195*60*1.6mm

Finished board size: 195*60*45mmUndistorted power: 400WMaximum power: 600WPower supply: DC plus or minus 20-50V (recommended voltage -30V 0 +30V)If you need high voltage (maximum plus or minus 90V), please rep the electrolytic on the board (change the with high withstand voltage)There is a p on the board labeled 2K and 330, which means that 2K adjustable s can be soldered here, or 330 s can be soldered.104 is the 104*6 is here there are 6 components welding 104 = 0.1uF , 221 is 220pF , 220 and 330 is the resistance unit is Europe 104 * 6 means that these six ps are welding 0.1uF . OUT is the output. 104 represents a 0.1uF .Capacitance withstand voltage is 50V0.22 is 0.22R cement 0.22 is 0.22R non-inductive cement 10 and 68R are 1W watt 0.22R is 2W watt, and 5W can be 1uF-10uF polyester and electrolytic can be welded, we use 4.7uF, electrolytic should pay attention to polarity, 4.7K large, with 2W and 5W will do
