Hello!
The tx1003 came out after I was getting stuff from S&B so I don't know the color code. I am sure Jonathan at S&B will soon send a reply. Try re-sending your e-mail to him to be sure he has received it and give a phone call if needing the info quickly.
Norm - Good to see your name! Thanks for posting that info and I hope all is well with you. Still have that x-dac here from many years ago.
Thansk!
John
