Just as a follow-up, the second source that I mentioned above got back with me within an hour. I don't know if he has the parts yet because he needed the part number for the valve to check. But he definitely still carries Jobo parts. I'll post back what I learn. Jobo owners need sources of parts better than Omega/Satter. I expect to hear back from JoboMan soon too. As I said, he's a really nice guy and I have seen posts by others in various forums who have been very happy with him.
