It's the start of an amazing journey. I am happy you are continuing this thread, the great repository of JH-636 information. I have collected a lot of other information in my refurbishment of my JH 618 and my JH 636. I am building some new Mic Pres this week! Let me know if you have any questions- and look for the Facebook groups on MCI 500 and 636 consoles. Lots of great information to share with you... Bonne Chance!
