First connect only the TT to the pre-amp and amp only (no other components). If the hum continues try a cheater plug on any power cords that have 3 prongs starting with the TT then the pre followed by the amp. I had a hum from my cdp and lifting the ground (3rd round prong) from the power cord fixed it. Cheater plugs can be had at almost any hardware store. That being said I do not recommend cutting of the ground from the power cord especially if its an upgraded cord (then do it or have some one do in the connector as not to devalue the cord). That way you can put it back if you should ever decide to sell it.
Ground loop hum from Turntable
Not sure what is causing this but, i took home a Rega P3-24 to demo, hooked it up to my Plinius 9200 and was getting a loud hum. I noticed Rega does not include a ground wire on there interconnects. My dealer indicated that the ground is done internally. I am limited as to where i can put this table. I have a Billy Bags AV component rack and all my gear is on this rack including my TV. I assume this hum is being picked up from the other components. Any suggestions as to what i can do to greatly reduce or elimiate this hum. Thanks for your input.
