Question about Audio Players & Recorders

1 Answer

I have a Denon DP-51F Turntable that recently developed a speed control issue when playing. I noticed the "lock" indicator also flickers when the speed becomes erratic. It's direct drive, and I should also mention was moved with our houshold via moving van. I loaded and unloaded it myself.

    My Denon DP-51F started revving up suddenly a few years ago, indicating that the magnetic servo feedback system supposed to give exactly 1,000 pulses per revolution (situated on the inside of the outer rim of the platter with a tone head mounted to record the signal) failed to provide the 555.6 Hz that is used to stabilize the speed at 33 1/3 rpm. Tried to adjust the tone head closer to and further away from the magnetic strip, but in vain. Have found no cure and the beautiful piece of equipment is just gathering dust. Too bad for such a good turntable.

Hi. I also have a DP-51F and am experiencing severe problems with tracking. My sense is that the tone arm may be damaged. Would you be willing to sell parts from your turntable if you're not going to repair it? Let me know as I would be interested.

Adjust pitch


Register (free) at Vinyl Engine and download the service manual. The adjustment you need to do seems fairly simple. You will need a turntable strobe disk to get the the speed right, unless you have perfect pitch.

In my DENON DP-300F tone arm don't come back after playing record. It just stays in the end of record? How can i fix it?


A lot of decks don't actually do that anyway. But if it previously did this then it's probably a mechanical problem. Removing the bottom of the turntable might show up the cause of the problem.

The answer lies in that 33 button. The connections to the should be followed and investigated why it does play correctly when held.

Denon DP-297 Turntable Tone Arm Skating


There should be a weight on the end of the arm, this needs to be adjusted. Some have numbers on them, increase the number shown. To get it to work right you will have to do it by trial and error. Increasing the weight in small steps, then playing a record. The trick being so it stays in the groove, but not too much so it rumbles on the sound. You will need to repeat the process several times till it sounds right and stays in the groove.

There are only two types of records available like 17 and 30. the size 30 will be as same as the turn table plater's size. 17 will be in half sized of the 30.
OK

How do you adjust the tone arm on a Denon DP-47F turntable? Thanks Cosmicharlie


Basically, like almost any other turntable.

Look up the recommended tracking force for your cartridge/stylus.

Unplug the power to the turntable.
Using the tonearm elevation control, raise the tonearm.
Manually move the tonearm in toward the platter.
Manually rotate the platter ClockWise a few turns to disengage any cueing mechanisms.
Set the Tracking and Anti-skating controls to 0.
Disengage the tonearm elevation control. The tonearm will either float or drop. This is why we have no power, just in case it hits the platter.
Adjust the counterweight until the tonearm floats exactly horizontal. Use the flat portion of the tonarm rest as a gauge.
Return the tonearm to its rest.
Dial in the prescribed tracking force and anti-skating. Play records.

Turntable speed erratic


It is likely that grease has hardened and as the gears rotate that grease is interfering with normal operation. Take the unit apart and have a look at the drive mechanism, if there is something in the gears you should be able to see it.
