New and unused power amplifier module, originally sold by RS Components, but now discontinued. These were found during a workshop clearance. They are the PL version of the MTK100, PL meaning that they have the mounting plate fitted. Using only a few external components for a power supply, and a suitable heatsink, this module will provide100 Watts RMS into 4 ohms, and I have already built a couple of powered monitors using two of them. The rest are now up for sale here.. The screen grabs shown in the listing are from the original specification sheet, and I will provide a printed copy of this with the items.
