Running Tab V7X modules on more than 220v, problem?

Hi.

I just bought a used Sonic World rack for my V77 and V76 modules which works great, especially since it has the external gainswitch for the V77´s built into the rack.
One thing I was wondering about is to run the V modules on more than the 220v that they were designed for?
I heard that the modules could be harmed and since I have about 236v coming out of the wall and know that other rackmanufacturers limit the voltage down to 220v inside their racks i am a bit worried.

So, does anyone have any experience with any problems or could see potential problems pop up?
And if I need to regulate the wall voltage down to 220v, does anyone have a curcuit for that?

Thanks.

Filament is the issue here, run the conversion math and see.....

236/220 = 1.07273 • 6.3 = 6.7582 as an example, if that's how those work and how yur rack is set up. 

I'd be surprised if the rack didn't have some adjustment possibilities.
