Wish I could help but I'm clueless: I do have some of the original CS80 documents lying around the house so I will take a look and find out: if there is a difference, I will FedEx them to you. Give me about a day or so to see if I can locate them here. Cheers!
Thanks. I’ve never known of difference versions of the CS80 service manual, but I guess it’s possible. The silkscreen on the board matches the manual too - and not the actual part that was on the board. I’m looking forward to someone having the time and ability to take a look inside their CS80 and let me know what they see. This is why it’s always good to be working on a couple of them at a time and I had to go and actually finish the other one that was here and give it back to its owner. How silly of me!
