kgallen Posted January 14, 2022 Report Share Posted January 14, 2022 Twin TOSLINK plus coax output board. Transformer isolated coax output based on Sony MDS-E10 ‘pro’ output stage. The pulse transformer is the most expensive part by far (about 4GBP) but the PCB is padded out for a couple of options to mitigate against availability issues. This project is partially @BearBoy’s fault 😆👍 I subsequently found the part Sony use for the Coax RCA connector so I will redesign the PCB. I also missed one capacitor in the coax circuit. No real consequence but I’m a stickler for detail… I originally designed this for my MXD-D4 to provide TOSLINK output from both the CD and MD sections. However with @BearBoy’s input I added the coax output and selection jumpers so it can be used with an MD-only machine and thus add twin TOSLINK and coax outputs. Just a DIP 74HCU04 IC goes in the socket. Quote Link to comment Share on other sites More sharing options...
