Hiss and Hum sounds are different. Hum can be casued by improper grounding, loose contacts, motor/plinth/platter vibrations et al. BenC's suggestion is one solution you can work on. One remedy I normally do is to use jumper wires with alligator clips and terminate all vibrating/moving parts into one common ground (normally, the amp's chassis) It may be an eye sore but at least this will help you to find the source of the hum.

HTH.
