150 Watt MOSFET Mono Amp (KIT33S)


Our 150W MOSFET Amplifier Kit has proven to be one of our most popular kits ever since its original launch in 1982. The kit is ideal for a wide range of applications, including guitar amplifier (it was originally design for this purpose), disco amplifier, home hi-fi or sub woofer.

Voltage: +/-55V DC (max)
Current: 2.5A (8 ohms)/5A (4 ohms)
Power Output (1kHz continuous sine wave): 100W RMS into 8 ohms/150W RMS into 4 ohms
Frequency Response: 20Hz to 40kHz
THD: 0.01% at 1kHz
Input Z: 47kohms
Sensitivity: 860mV RMS input (2.43V pk - pk)
