Default filament rails

Is there any hum problem if the ac filament rails are very close to the star ground?
Something like this in foto.

If you keep the AC wires tightly twisted, that will minimize any noise pickup problem. If you're really worried, get a few inches of braided tube, slip it over the filament run near the star ground, then ground it.

Thanks SY

I have twisted them very tight.

I was thinking to try with aluminium tape.
Hope I'll not have hum problems.
