Just to be clear, the noise is coming from the motor itself and not through your speakers?

This is what I have found: The transistors used in the Denon DP6000 are 2SC458. They are notoriously noisy. The recommended replacements, among many are KSC1845, BC549, BC550.
The articles from AudioKarma related to repairs for noisy amplifiers. The Japanese site dealt with rebuilding the Denon DP6000 amongst many DD rebuilds.

Redglobe, Good point about the transistors. I am sure you realize their description as "noisy" has to do with electrical noise, not audible acoustic noise. I replaced all of those transistors in my DP80, or rather, Bill Thalmann did. Bill said something to me about the original transistors being subpar. The DP6000 will work better with upgraded transistors, but I don't think they are the cause of the noise the OP is hearing.
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 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?
