If you have an external quality downstrip transformer available, just use it.
Only disadvantage is, you have an additional external device to carry around.

How old is your MKS70 ?
Check the internal PSU for stable voltages and the caps.
Bad voltage can damage internal circuitry, the display is the critical part in the MKS70.
It´s a VFD (and unavailable like the Oberheim Matrix12 /Xpander VFD displays).
If it fails you have a prob to get a replacement.

good luck w/ your MKS, it´s a great sounding machine ...

the MKS70 transformer ?
