Fixing a Kenwood KD 491F turntable

sounds like missing weight or needs adjustment

You have got to lift the table on which the vinyl is placed underneath you will find the belt laying loose on the bottom of the table is a pulley on you fit the belt then on the right hand side or rear is the pulley on the motor which the belt also has to be fitted then carefully lower the so as not to let the belt come off again this should provided the belt is not stretched or snapped then it will have to be reaplaced

This should help.....probably not your model, but same in theory...page 7.

I know this isn't the same model as yours, however it shows what I would describe to you on page 7. Hope this helps.

Your turntable is belt-driven, it's likely that the belt just fell off. The belt lives under the turntable. On my turntable (a totally different model) the turntable lifts off.

The tonearm lift is no longer level as it should be and the arm is sliding along it under gravity as the arm lowers to the record. Has it received a knock?

Have a close look to see whether it has been tilted slightly. That would be enough to give the problem.

The belt normally wraps around the bottom of the metal platter. Put the platter back on the turntable, and you'll see holes on opposite sides of the patter. Just pinch the belt out a little, and wrap around the motor shaft - should be a brass shaft assembly.

Appreciate the additional information.

To recap what you need is a receiver that can accommodate:
4 - Pioneer S-DF1-K (15-100W, 8 ohms)
1 - Pioneer PD-F407 25 Disc CD Player
1 - Pioneer CT-300 dual tape deck
1 - Kenwood KD-491F turntable

Possible choices are (keeping in mind that the power output should be less if not equal to 100 watts and a turntable/phono input):
i. Onkyo TX-8522 Stereo Receiver;
ii. Yamaha RX-397 100 Watt Natural Sound AM/FM Stereo Receiver;
iii. Sony STR DE695 AV receiver;
iv. Teac AG-790 200 Watt Stereo Receiver;
v. Denon AVR 888 - AV receiver - 7.1 channel.

Some of the above also includes feature(s) to hook up to your video system. Some may even require a fifth speaker (subwoofer).

Incidentally, you can also choose another brand/model even without a turntable/phono input. As initially posted, a turntable/phone to line level pre-amplifier is only required. Here are some examples:
a. XP200 Turntable Preamp - Nano Series;
b. Pyle® Pro PP999 Phono Preamplifier;
c. Pro-Ject Phono Box Turntable Preamplifier;
d. Radial J33 RIAA Turntable Preamp Direct Box

Good luck with your project.

Hi again,

It would seem that you posted the problem here also. With your kind permission, I will repost my excerpts of my responses that others may benefit on similar concerns.

A. Most current receivers no longer include a PHONO input. Perhaps what could be done is to purchase a phono to line level pre-amplifier to go along in your purchase for a new receiver.

I was made to understand that the Pioneer SX-1600 is prone to speaker output problems which could either be:
1. the speaker relay (protection); and/or
2. the amp, STK4191II Stereo Module.

Either should be relatively easy to work on and perhaps you can try the services of a locally available qualified electronic technician since the repairs would not be too specialized. The service manual may be of help (or at least a schematic , they may be downloaded from here and here).
