Having a weird issue to track down with my Beogram 1700. Every time, and I do mean every time I try to play a 33RPM record, the speed is incredibly fast (I don't have a 45 laying around, but it feels faster).
I searched here and found a number of threads talking about switching out the belt, which I did. But no change. I do have a theory though!
It seems it has something to do with the weight? If I put on an old album that's super light, the only way I can get a consistent (correct) speed is by adding 2-3 similar albums underneath. If it's a more modern 180 gram album, I just need 1. Even doing this, I still go into hyper-mode the first time, but once I pause and restart, it works for the entire side every time.
If I have to pause before flipping sides, it again goes into hyper-mode on restart, every time.
I am grateful that I can at least get through an entire side without it switching speeds every song (which it did every time before), but I'm hoping anyone has some advice so I don't have to keep stacking albums.
Thanks all!
Is the belt slipping on the motor pulley?Did you fit a correct belt or something from ebay etc. that merely looks somewhat right?Did you replace the speed setting trimmers?Did you replace the capacitors?Check for cracked solder joints at the PCB?

I got the belt from a local repair shop in London before I moved away. I can't tell for sure obviously (should've bought from you), but it does appear visually to not be overly tight or have too much slack (and when I run the unit without the top platter, I don't see evidence of slippage).
No solder joints seem decayed, but what about the speed trimmers? What exactly are they? \
Thanks so much Martin.
The trimmers are the electronic components that allows you to set (fine-adjust) the speeds. Certain types are known to fail due to age.They are included in the servicekitPlace a finger on the motor pulley as a brake, and rotate the subplatter by hand. Note if the belt slips around the motor pulley. It should have a fair amount of friction.But, with all due respect, unless specifically working with B&O it's very unlikely that any local repairshop will have anything but standard belts.
