Custom Mono 200W power amplifier board 1943+5200 high-power pair transistor rear stage PCB empty board

The base pin spacing of 2P and 3P is 7.62mm. The 200W mono amplifier board has a high power of 1943+5200, and Toshiba has an empty PCB board for the rear stage amplifier board

Tips:

This connection is an empty PCB board without any parts

The board is: a single channel amplifier board without rectifier circuit, which requires dual channels. Buy 2 pieces

The circuit design uses A970/C2240 high voltage audio pair transistor double differential circuit, and A1145/C2705 for voltage amplification, driving the use of medium power pair transistor A1837/C4793, and the output stage uses A1943/C5200 high-power Toshiba pair transistor. Wide power supply range, DC positive and negative 20V-50V can be used, as long as sufficient power is supplied to easily reach 200W. Good sound quality, extremely strong driving force, pushing 15 inches without pressure!

PCB size of length, width, and thickness: 120 * 60 * 1.6mm

Power amplifier board size: 120 * 60 * 45mm

Length, width, and high actual power: 200W

Power supply: DC positive and negative 20-50V (recommended use: -30V0+30V). If high voltage is required (maximum positive and negative 90V), please replace the electrolytic capacitor on the board with a capacitor with high voltage resistance

0.22 is 0.22R, insensitive cement resistance 10 and 68R are 1W watts resistance 0.22R is 2W watts resistance, and 5W can be both 1uF-10uF polyester capacitors and electrolytic capacitors can be soldered. We use 4.7uF, and electrolytic capacitors should pay attention to polarity
