STK1080+

Replaces STK1070, STK1080

This module is listed for individual sale. A good upgrade is to buy two.

Ready to use module replaces the Sanyo STK1070/80 but more robust. Be aware, this is the 10 pin STK1080, not the larger 12 pin STK1080 II. Fits the Akai AA-R42 models and probably a lot more.

NOTE: The STK1070 and STK1080 are larger than the STK1030/40/50/60 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:
120 watt	400Hz	0.0040% 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.
• NOT 35 years old or counterfeit. Sanyo quit making these in 1983.
• YES, every module tested in our Yamaha CR-1040.
• YES, 4 ohm speakers are OK. We use 15 amp outputs vs original Sanyo 10 amp devices.
• YES, gold-plated PCB. PCB Finish, ENIG (Gold), compliant with IPC-4552.
• YES, free USPS shipping in the USA.

Hand tools and simple solder skills required. Technical knowledge required. No returns and limited support, this is not for beginners. We do supply instructions and helpful test tips.
