Replaces the TA-100W, TA-80W in the Kenwood KA-7500, KA-8300, KA-9800
This module is listed for individual sale.
Ready to use module replaces the Kenwood TA100W in the KA-7500, KA-8300, and KA-9800. The TA100WA+ for the KA-9100/9150 KA-770D is ready and listed separately. Repairable, discrete design. Carefully designed to fit the same mounting holes, no drilling or grinding necessary. Built with modern output transistors. These same power transistors are used in the 140 watt per channel Marantz SR8012 and the Yamaha RX-A2070.
NOTE: The TA100W and TA-100WA are very similar, but do not run at the right temperature if swapped.
