Hi – I recently acquired a Beogram 1700 and have noted audible (though subtle) speed variation. With an app, I was able to confirm excellent speed accuracy (33.33 in a measurement taken today) but w/f is problematic, coming in at .37. The belt that came with the table was somewhat stretched and slipping from time to time so I replaced it some weeks ago with a belt (talc applied). Any advice on how or whether it’s even possible to improve (i.e., decrease) the wow and flutter? According to B&O’s official Beogram 1700 specs…
Wow and flutter DIN < +/- 0.09 %Â Â Â (Really?! I’m not even close.)
I’ve used the app I mentioned earlier, called RPM, on three separate turntables. Results: My Beogram TX2 comes in at .26; my Fluance RT85 comes in at a very nice .15; my Beogram 1700 (as I said) comes in at .37.
Any and all help much appreciated.
