Many Thanks for all suggestions and Help.

Hi
There are a few things that you can do to help and isolate the problem.
1)Is the hum present with or with out the cartridge connected - to check that it is not the cartridge since these are a common source of hum.
2)Is it on one or both channels
3)Is it possible to see if you have any hum with an alternative pre amplifier connected.
4)Check all mechanical connections and clean if possible. That is all the input and output wires.
5)Can you check if all earth connnections are connecting properly. Where these are soldered or bolted are they secure.
6) Does the hum increase with volume increases.
7)Does touching the turntable or cartridge or preamp alter the hum.
If you can check the above it should help isolate the problem.
