SPDIF RCA to (Optical + RCA) Adapter

This circuit might be of use if you have lots of audio gear, seems like a nice simple circuit that gets the job done.

“I needed to connect one RCA digital SPDIF output to a TOSLINK optical input. As many times, a simple device with that functionality was again much more expensive that what I believed reasonable. I found some circuits on the net and I adapted those designs to my needs.”
