AV9000 - a vintage product ? Boy, I must be getting old.. Martin

Welcome to Beoworld ! The wiring depends on the mains voltage. It's all in the servicemanual, available for download for silver and gold members. Martin

Boots, Welcome to Beoworld ! The Beocenter 5000 is actually one of the rarer machines, lovely and superb build and quality. I can't help you with the turntable dustcover but I have a few brand new original hinge pieces in stock, they always break where they grip into the aluminum lid if forced to close to fast. I can also supply belts for the turntable

Thanks for the input Cozza ! Well, I have a couple of these motors, brand new. Jandyt, maybe if you'll let us know about what size it is ? Martin

If the drivers are originals, don't one of the fasteners on the chassis have a red insulation washer ? That would be the positivie terminal (orange wire in most CX50's, I believe) Martin

PM til Lennart ! (Din inbox findes til højre, helt i toppen på siden) Martin

Joe, Welcome to Beoworld ! The 4Volts sound about right. The problem is not the motor but merely seized lubricants. You need to take apart the mechanics and clean everything. Add a small amount of fresh silicone grease and it will run fine again. Remember to mark where the cog wheels grip each other and the tray, they are coded and need to get back

Putting 100 ohms in the leads will probably take the level down enough to make it practically useless but the ohmic value would be correct for the impedance and trying won't hurt anything. A resistor of 1/2 Watt could get hot but try with low volume first and feel your way. The correct way would be to use two resistors - one for each channel in

The spring sits inside the nylon wheel at the potentiometer. I normally use a pair of U70 for testing headphone outputs and never had any problems but they probably have an even higher impedance, I don't remember. Anyway, putting a series resistor in each channel won't hurt anything. Martin

The logic is fine ! Though I tend to lean more towards a theory of aging power supply caps. Do you have the hum also when only speakers are connected ? Dial string is sold by the meter. There's really no good alternative to real dial string though I've heard some people have used fishing line. I haven't tried this myself so I really can't
