Denon DP-47F
Fully Automatic Direct-Drive turntable (1985)
Description
The Denon DP-47F features a low mass tonearm with Q-damping method.
Low frequency resonance caused by the cartridges compliance and the effective tonearm mass is electronically damped both horizontally and vertically to effectively suppress crosstalk and inter-modulation distortion.
The dynamic servo tracer maximises the performance of the low mass tonearm and results in a record reproduction of excellent sound image with minimum noise and distortion.
By pressing the locate button, the tonearm is moved to any desired location where the record play is started.
The DP-47F also features Denon's quartz bidirectional servo and electronic braking system combined with a magnetic recording detector.
The quartz lock ensures stable performance of rotation and a sharp operation.

1.) You can adjust the vertical swing of the tonearm by the small screw at the back end of the tonearm. Try half a turn counter clockwise.
2.) Possibly the tonearm on your TT is bent. Have a close look from the side if it is sloping down from it's rest. If yes, it has to straightend. You don't need to touch the screw in this case.
Send me a PM (German or English language) if you need more advice.

Same problem w/DP-51F
Submitted on November 17th, 2009 by flylooper99Manfred, I have a (new to me) DP-51F that is giving me a HUGE headache - perhaps you could help. I've set up the tonearm many, many times as indicated in the owners manual and the cartridge keeps skipping. In actual fact, it won't even find the lead in groove. The only way I can actually get it to play is to dial in the maximum tracking force on the anti skate. Even then there will be at leat two or 3 skips per track. I'm using and Ortofon OM 30 cartidge (also tried this with an AT15LC with similar results). This is one thing I noticed: when looking at the cartridge/stylus closely from the front when it is tracking on a record, it almost looks as if the stylus is being drawn to the left of the cartridge enclosure (i.e. towards the spindle). I'm not sure whyt this is happening as the arm moves freely in all directions and doesn't seem to be retricted in its movement towards the center of the platter as the stylus tracks the record. Any idea what c the problem could be?
As a follow up: I've reached the conclusion that it's the electric damping that is "over damping" the tonearm movement and thus requiring more side force to move it accross the record, hence the skipping. Would your solution, i.e. adjusting the small screw at the back of the tonearm also solve this problem? It would seem that my problem would require a electrical rather than a mechanical adjustment. Thanks!

Submitted on April 5th, 2009 by justinlacisSame thing here, but the auto functions on mine do not work at all. I will be attempting a full refurb of mine.I will keep you posted on any solutions.

Submitted on April 8th, 2009 by LembeckerSame as above. Maybe the control board is dead. Contact me if you need more help.

Submitted on November 17th, 2009 by LembeckerPossibly the anti-skate force is too high and the electronic control needs adjustment. Set the anti-skate force to zero at the ant-skate dial and see what happens.
