Whadda WMAH100 (Velleman VM100) - 200W Discrete Mono Audio Power Amplifier Module

The Whadda WMAH100 (previously called Velleman VM100) is a PRE-ASSEMBLED discrete mono audio power amplifier module that provides 200W music power output (100W RMS @ 4 Ohms). Excellent value for money and gives great results. Heatsink included.
Fully discrete design using TIP142 and TIP147 epitaxial Darlington transistor pair. Board includes built-in DC rectifier and smoothing circuit components.
A suitable mains transformer (Order Code 12030 or TR8040) is available to purchase separately.
Also available in SELF-ASSEMBLY Electronic Kit format without heatsink (Order Code K8060).
