Dan, Spring barrels can be dangerous if you don't know what you're doing. I have never had the nerve to do one myself as I have heard stories about the spring popping out and the possibility of serious injury to hands and fingers. I have always sent mine to a qualified expert to have them replaced or repaired. Although, some of the Phonograph books give detailed instructions for repairs. I'm somewhat of a newbie when it comes to repairs on these machines. I'm sure that some of the seasoned professionals in the group can offer some sound advice.

I had just played a record and went to play a second and the spring would no longer wind. The crank just moves loose. I did not hear the spring break, so I am thinking it may have come disconnected inside the spring barrell. Everything is so large and I've never taken one apart before. Is this an easy thing to check? Is the mechinism in a B250 unique to that early machine or could it be interchanged with another? Thanks for any advise you might have.
