My Beogram 5500 has begun stopping about 1" from the end of the record, and staying there, skipping while it plays. At first I thought it was a bad record until it did it consistently on different records.
*edit* ( The SM is only explaining how to manually operate the mechanism without power here, I thought it was how to adjust arm travel...you can ignore this part ) I had a look at the service manual & the arm travel adjustment seems like a strange procedure: rather than adjusting a set screw like on most TT's they want you to turn the gears? I don't understand how this limits the inward travel of the arm. Before I mess with adjusting it can someone confirm that is how you're supposed to do it?
I also cleaned & relubed the 2 steel rails, used white teflon instead of lithium: I noticed the arm is catching a little on something as I slide it inward on the rails. But it's smooth sliding back out, feels like a switch? I hear it click. At approximately the spot the arm stops, I think.
I searched & found this thread:

will open the 5500 up again & see if it's that 1/2 mm plastic bit I need to trim off. Thanks for any advice!
It seems to be playing back fine now, but I can't advance the arm using the LIFT button past that final 1" or so ( before the runoff groove).
I suspect that piece underneath is just starting to act up, will open the 5500 up when I have time & snip off .5mm as Marton suggests in that other thread.
It seems my problem is different than the 1609 part underneath bending & interfering with 1604.
When I move the sliding chassis (11) inward by hand, the pulley 1634 catches hard on something an inch from the end, which triggers the cam wheel 1606 to move and activate something.
Moving the sliding chassis (11) back out, it hits something softly at the same spot, which again causes cam wheel 1606 to activate something. If I press softly down on 1604, it eases the hard catch, but if I push too hard it won't activate cam wheel 1606 to do it's thing in either direction.
It appears 1604 is interfering with the pulley 1634, by catching on it where it's supposed to activate 1606, moving inwards only. This seems to be what is causing the tonearm to stop 1" from end-of-record and skip forever. Hmmm, do you think a warped 1609 has enough force to cause 1604 to push up and stop 1634 from moving the tonearm?
Thanks! Cleaned this whole thread up, lots of edits
