Michael It's funny, I read your post literally 45 seconds after opening up the clock and discovering the NE-2 seemed to be soldered in and wondering if the only recourse was to desolder it. Someone near me on this list who has some expertise wrote and offered to take a look so I think I'll let him desolder it and take a look. I can't be trusted (with this) with a soldering iron. And thanks so much for letting me know you have the parts if I need them. That's really comforting to know, honestly this clock is on my list of ten things I'd try to save if my house burned down (excluding people and pets, obviously).
And, wow, your MOD-SIX_SLW looks awesome (as do your many other creations)! I would buy a MOD-SIX_SLW in a heartbeat if I figure out how to source the tubes (but, don't worry, I'm not asking).
