[sdiy] MKS-70 Switch internal transformer from US 117 to UK 240

[Richard Atkinson]

If it's like the MKS-80 and the JX-10 I have here, the MKS-70 will use an 
IEC C9/C10 connector in both its US and UK incarnations. If you can find a 
UK C9 lead you should be able to use it with your MKS-70 once you have 
rewired the transformer.

Check the transformer very carefully when you do the rewiring job. Many 
multi-voltage transformers have two sets of primary coils, which are run in 
parallel for 110V and in series for 220V/240V.
