Amazon.com: Signstek HiFi USB to Coaxial S/PDIF Converter …

P.S. For those who’d like to give it a whirl, the list of original values I believe are as follows: (5) 22-ohm, (3) 100-ohm, (1) 220-ohm, (1) 300-ohm, (4) 1.5K-ohm, (1) 5K-ohm, and (1) 1M (meg-ohm). Should be a total of 16 in all, but please check your particular board with a meter and verify due to the possibility of running production changes.
