200W Discrete Mono Audio Power Amplifier Electronic Kit

Discrete mono audio power amplifier. 200W music power output (100W RMS @ 4 Ohms). Excellent value for money. Gives great results. Ideal for active speaker system or subwoofer, guitar amp, home theatre systems, instrument amp, etc.

Fully discrete design using TIP142 and TIP147 epitaxial Darlington transistor pair. Board includes built-in DC rectifier and smoothing circuit components.

A custom pre-drilled heatsink (Order Code HSVM100) and mains transformer (Order Code 22530) are available to purchase separately.

See VM100 for a PRE-ASSEMBLED version of this item complete with heatsink.
