Denon DP-7F


The features of the Denon DP-7F include:

Silent, fully automatic operations with the use of a microprocessor controlled contactless servo tonearm, which ensures safe, easy to use automatic operations with little loss of sound quality.

Speed is controlled by the Denon-Quartz which is the combination of the high precision magnetic pulse detection method, the most sophisticated method of FG detection, and the Quartz Lock.

The lightweight straight tonearm that performs excellent tracking has a T4P connector, allowing easy replacement of cartridge.

Balance Weight For Denon Dp-7F

I bought a Denon DP-7F DD turntable and later discovered the tonearm banance weight (counterweight) is missing,
wondered if anyone had one available? Looks like it just sits on a peg at the rear of the arm, no adjustment whatsoever.

I am missing the same part, have you found one ?

DP-7F Parts/Repair

Hey, do U still need your Denon turntable fixed? I got spare parts. What happened was, I bought one on Ebay that got slightly damaged in shipment. The platter was left on the hub, and when it got jarred in transit, the platter broke free and wrecked into the tonearm. I powered it up and it the electronic motor drive system is good. Idk but the tonearm might be okay, just a long scratch on the left side of it, and a chip in the back plastic housing. The platter sometimes won't turn automatically unless you give it a push. From there out, it seems to be running right. The bearings might be shot, in the platter and tonearm. Anywho, if I don't turn it into a working unit, I will part it out. Got an Ebay account? Search for Denon DP-7F Turntable/Record Player on Ebay, in the next week or so. It'll be listed, I'd say, between now and May 14th. Otherwise, let me know if you want to send yours to me and I'll fix it, (real resonable) using parts off of the other one. For turntable shipment, remove the platter and counterweight, lock down the tonearm. Wrap a wire tie around the tone arm to secure it to the rest post. Package it the original way (Instructions are right on the DP-7F box lid). Or else put the platter and counterweight in separate bubble wraps, and cushion the rest of it with bubble wrap, in a sturdy box. You could comment here, and let me know if you want to send yours out, or wait and see if I end up selling this one for parts only, on Ebay, with no reserve.

My hostage is this stuffed teddy beat

Hey my table I just bought is turning the wrong dang way. I suspected something when bought it but years of video killed the radio star I must have lost my orientation, and bought the dang thing anyway. Who knew when in the store which way was north? It was turning! My kidhood disc spinning dna memory gene had temporarily been recessive or should I say overcome with greed at having found such a chick magnet for a mere 5 spot. It's a Denon DP 7F. When I got home I put the doobie brothers on and the dudes were saying "don't inhale" before I realized it was playing backwards and the needle was trying to leap off the disc like a cat on hot asphalt, back toward the arm rest. Can any of you shiek the freak record people give me a word?
I have a screwdriver, bright lightbulb, and lots of time.

Denon DP-7F Turntable Running Backwards

I have some background in which I can help you with this, to a degree. However it gets to a point where I'm in over my head. I thought this might help some, so here goes:

According to the service manual .pdf file, there are 2 electronic control sections that drive the turntable motor. There's the Servo Control Unit (KU-5520) and the Motor Drive Unit (KU-5530). There are pos. and neg. 5 volts dc power supply section, that converts the incoming ac and feeds the servo and motor drive units. Also it feeds the +/- 5vdc to the tonearm control unit, which we will not discuss [ :) ].

There are a few adjustments on the motor drive unit circuit board, and a proceedure for checking and adjusting the output of the motor drive unit. You will need not only a screwdriver (possibly phillips but I'm guessing a very small flathead) and bright light, but also an oscilloscope, or at least a volt meter.

If I were you I'd check with the previous owner to see if they know when and how the problem happened. Did it just one day start to turn backwards, or was someone screwing around with the motor torque adjustments without knowing exactly what they were doing, that caused the problem.

The adjustment procedure is fairly simple. However you need the right tools.

You could try (if possible -- well I don't physically have one of these turntables and the manual doesn't have any pictures of the motor and how the wires are connected to it)... You could try reversing the 2 wires where they connect to the motor. However, this is not a "regular" motor. It is called a linear drive motor and I don't know what they mean by that, exactly.

Reversing the phasing of the motor drive output pulses, you would think, would reverse the motor and platter direction. This is where I'm in a grey area as I have no detailed experience with the linear drive type of motor. So, idk, it's possible maybe reversing the wires could cause something erratic to happen. Therefore, someone who knows more about this might be able to comment on this, and take it a step further.

So you say it runs backwards. Does it seem to run at the proper speed, or is it waivering? If the speed seems under control but just backwards, then the PLL quartz lock "servo control unit (KU-5520)" might be okay. In this case I'd suspect the problem is somewhere in the motor amplifier "motor drive unit (KU5530)."

Good luck.
