It's really hard to adjust the speed on my Amadeus GTA. There's a tiny little resessed screw on the back that I don't have easy access to. I have to get a small screw driver aligned with the screw head by feel, not by sight. Pain in the butt! After I get the screw driver aligned with the screw, no problems adjusting the speed. (sometimes it needs a little tweek)
First, is there suppose to be an external knob so that I could adjust by hand? I purchased mine used and there is no knob.
Second, if no knob, any secrets to finding that screw slot?
That's my only complaint with the turntable. Other than that, it's fantastic.
