STK1060+

Replaces STK1030, STK1040, STK1050, STK1060

This module is listed for individual sale.

Ready to use module replaces the Sanyo STK1030, STK1040, STK1050, STK1060, but more robust.

Be aware, this is the 10 pin STK1060, not the larger 12 pin STK1060 II.

Fits these models, and probably a lot more: Onkyo A-8, Technics SA-401/SA-505, Mitsubishi DA-R20

NOTE: The STK1030/40/50 family is smaller than the STK1070/80 family.

Compact design, same mounting holes as the original Sanyo. With just eight solder connections, it takes a professional tech about 10 minutes to replace this module. Typical current gain 8,000-20,000 vs original 5,000. 15 amp, 160 volt transistors INSTEAD of the original 10 amp, 110 volt part. These same power transistors are used in the 140 watt per channel Marantz SR8012, Denon AVR-X7200W, and the Yamaha RX-A3070.

Typical performance into 8 ohms with the tone controls bypassed:
45 watt 400Hz 0.0020% distortion
  • NO bias adjustment, preset during testing.
  • NO paste needed, we supply silpads.
  • NO drilling or grinding to fit, only 4mm wider than the Sanyo.
