OK 4x4F150.....I ordered a new pot. Just removed the old scratchy one. I dont have a neat Hakko sucker so it was going into careful destructo removal mode!!
Using a small drill, drilling as many holes into the pot without hitting anything else, using some solder wick and flux to remove all of the solder I could. Then slowy prying the remainder of the pot out...she came out willingly!! Ha!
Now just need the new pot from mouser in a few days and we should be bcak to scratch free listening!!
Where there a will theres a way...

Hey guys! 🙂 Sorry about the delayed replies.
4x4F150 - That is terrific news! Well now I know how long these 9mm pots last, under continuous use.
Alex - Your removal work is looking good!

No gerber/EDA project files
I just stumbled upon this thread while looking around for a version of the O2 with modern parts. Am I being stupid or are there no gerber/EDA project files for the board in the google docs folder.

BTW, I still have AGDR's ODA in service several years after its design....still hitting it out of the park here. Had many amps over the years, sold many, but this improved O2 is indeed one of those rare amps that has stood the test of time here....

Hope this is what you were looking for, Pm me if this link doesn't works
I like the O2 design so I looked at a few posts in this thread. It's very interesting but it is not an O2 because of negative feedback from the output stage. That and all the other changes just makes it new design which could have been done without mention of the O2 except maybe some kudos for NwAvGuy.
