Jeff,
I still have a copy of a service bulletin I received from SAE years ago
concerning these transistors. The S1375 subs to 2SC1913 and the S1376 to
2SA913. NOTE-the lead configuration is different!!! Hope this helps.

Toshiba S1375 and S1376 used in this 1979 SAE 2200 amp do not seem to
be around anymore, anyone know some good subs for them?
Thanks, Jeff
