For Technics, replaces the STK8040 or STK8050.

This module is listed for individual sale.

Ready to use module replaces the Sanyo STK8040 OR STK8050, but more robust.

Fits the SA-424, SA-525, SA-515, SU-V4K, SU-V2A, and SU-V4A.

Compact design, with the same mounting holes as the original TECHNICS.

With just 8 solder connections, it takes a professional tech about 10 minutes to replace this module in the Technics SA-414.

Typical current gain 8,000-20,000 vs original 5,000. 15 amp, 160 volt transistors INSTEAD of the original.

These same power transistors are used in the 140 watt per channel Marantz SR8012, Denon AVR-X7200W, and the Yamaha RX-A3070.
