I have a Triumph B with 2-4min combination with a cygnet horn. When you play a cylinder the beginning is fine but as the cylinder advances to the middle it begins to slow and then start to repeat . Is there an adjustment that can be made or is the end bearing worn out?

There is a screw which adjusts the pressure the carriage puts on the half nut which might be the problem. The picture below is of my home, but the Triumph should be the same. The third screw adjusts the pressure, and it sounds like you might have to turn it anti-clockwise a fraction. When I make this adjustment, I like to disconnect the horn & remove the record from the mandrel to start with. It might take a few goes to get it just right, but once the carriage is moving across the mandrel correctly, re-attach the horn & make sure it's still working properly before trying a record. Not enough pressure on the half nut will cause the carriage to stop, but the record will keep spinning. Also make sure the half nut/s & feed screw are clean & lightly oiled. If you find it impossible to get the carriage to move across the entire length of the mandrel, it might be time to replace the half nut/s. They are made from a softer steel than the feed screw, and are designed to wear first.  |

I will try. Out of five machines this is the only one I seem to have a problem with. I'm am just hoping it is not a bend in the mandrel.
Thanks

I did solve the problem by replacing the End Gate Bearing and after a few adjustments it does play fine. I will say out of the five Edison's I have this one is the most temperamental.

My problem was the tension spring nut at the top of the cygnet carriage. When the record started, the cygnet neck was pointing sort of to the left. As it traveled across it started traveling downward in the middle and then to the right toward the end of the cylinder. In the middle of the record it was at its heaviest bearing on the carriage. So I turned the cygnet tension nut clockwise to raise the horn a bit to take weight off of the carriage. Since I had a rubber connector attached to a tizit, there was some play in the up and down motion of the horn on the reproducer neck. So lightening the horn weight on the carriage fixed the problem.
