Default earthing of turntable using isolation transformer

Hello guys, I recently bought nice turntable and experience hum as I run my setup through isolation transformer.
I dont want to induce buzz from network back, so I completely separated phono setup.
Is there some way to ground TT and still stay ground lifted through isolation transformer?

Connect the turntable chassis wire to the phono ground and ensure your system is earthed at least at one point, usually any touchable chassis MUST be earthed.
Using an isolated, transformer coupled power supply without an earth can cause electric shock from static build up!
