Hello all,   Hoping and looking for some help with my RX2. I picked this up a few months ago and was noticing that records would play for a few seconds and then go back to the beginning.   I figured it had to do something with the counterweight and I found out that it was just testing on the arm. Does anyone know how this is supposed to go back together? Do I need to glue something onto the arm?   Thank you so much for the help and expertise.
