My phonograph will play fine if it is opened, thus decreasing weight on the reproducer. When it is closed, it will slow down only when the reproducer is in the play position, even if a cylinder is absent. The limiting factor is when the rear part of the reproducer, as threaded, comes in contact with the threading on the back, which would cause the reporoducer to advance and play the cylinder. Any ideas how to adjust this so it can play through a whole cylinder without slowing down? Thank you.
Where you said you had just moved, I'm wondering if the TT base isn't sitting properly on the cross pin on the spindle. If this is the case, usually it just takes a bit of tuning the TT with the brake on until it seats on the pin. This would be best case scenario. Worse case would be if the move upset the horn height adjustment.
