Denon DP6000 crackling noise: Need Help

Hi All, I need some help. The Denon DP6000 that I just acquired worked great the first day (2 hours). The next day, it held speed. However, there was a crackling noise that emanated from the drive unit (the cartridge was not on the LP). The noise occurred only when the platter was moving. When the platter was stopped, with the power still on, the crackling ceased. (I played it only for about 5 minutes with the crackling noise.)

I know it is old and needs new capacitors. I will replace those immediately (Originally, I was hoping to put it off for a few months.)

QUESTIONS: Besides capacitor replacement, is there something else that needs attention? Is there a bigger problem?

Hi Lew, If you still have the parts list, I would be interested to know the replacement numbers of the transistors. Even if you do not have the corresponding OEM part number, it would be a reference for me.

Based on the Japanese site that I referenced, it seems likely that Bill Thanlmann replaced some of the diodes on your table. Those part numbers would also be helpful.

Dear Redglobe,

You may have covered this but just in case.

When I got mine it had 2 red shipping screws but I didn't realise it and from memory it may have done what yours is doing.

The Red screws are under the platter

Dear FastMick, Thank you for the advice. I wish I had those screws. When I drove it home, I tried to minimize the jostling of the transformer by putting pressure on the mounting screws. However, I could hear it occasionally clank against the underside of the top plate.

The crackling noise that I heard was erratic. Can you recall, did you encounter a similar noise?
