Product Details:
Based on the famous Sugden A21 pure class A amplifier circuit.
Mono 21W pure class A single-ended OTL power amplifier board
Power supply voltage: AC35V*1(mono 150W)
Output power: 21W
Quiescent current: 800mA~1000mA
Debugging method: Before power on, adjust the potentiometer clockwise to the end. After the power-on test sound is normal, turn it counterclockwise and adjust the voltage across the 1-ohm resistor to 800mV-1V.
Use Rubycon 50V/10000uF main capacitor imported from Japan.
Use new Sanken transistor C3284.
PCB size: 224*71MM
Net weight: about 0.24KG
Note: This is mono, if you need stereo, you need to buy two
