STK0080+

Replaces STK0060/70/80 in Fisher CA-880, RS-2010, SR6000, and IG0297

This module is listed for individual sale.

Ready to use STK0080+ module replaces the Sanyo STK0060, STK0070, STK0080, but more robust.

NOTE: The STK0030/40/50 family is smaller than the STK0060/70/80 family.

Compact design, drop in mounting like the original Sanyo STK0080. With just six solder connections, it takes a professional tech about 15 minutes to replace the module in a Fisher CA-880. Typical current gain 8,000-20,000 vs original 5,000. 15A output compared to the original 7A STK0060/70 or the 10A STK0080. These same power transistors are used in the 140 watt per channel Marantz SR8012 and Denon AVR-X7200W.

This part has been designed for and tested with the CA-880 and the Yamaha CR1040. If you are purchasing this part to use it in a CA-800, you will have to trim some sheet metal, as our part is slightly wider than the original.
