So I'm rebuilding an old recordplayer, sort of sliming it down and removing the "big box" and putting away the electronics inside so I can have only the record and the arm visible by itself. I have gotten everyting to work, but the grounding is all wrong so I got quite a bit of humming. If I touch the big metal disk the record is laying on (at least 1 kg of metal), I get a lot less hum, but still some.
Before it was not grounded thought the outlet, but it was grounded via the amp, which I don't have anymore. It also had a pretty big and heavy metalplate in the bottom, don't know if that could have helped in anymay, but I thought i mention it since I removed it. Now it's hooked to an active speaker via a new RIAA amp I bought for this and the ground cable is connected to the RIAA amp. The RIAA amp has a specific grounding hook, but it's not grounded thought the outlet either.
So, this is not black magic to me, but almost, so I don't really know how to approch this problem. Can anybody help me out? Thanks in advance!
