The power rating on them is 110V, is there any way we can switch to 240V max so that I can use them here. Is there a replacement power part available to change the power rating? I'm avoiding 240-110V step down transformers as they burn out real fast.

If you do a search for SLT66DTE13E there are plenty of suppliers as it's also used in the mk2.

JaS wrote:That depends whether you are trying to fully convert to the dual voltage version, or just get it working on 240V? The dual voltage version has a different PCB, voltage switch and transformer. I'm not sure why you would want to replace the regulator though? Once the transformer is changed the rectifier will be fed with 30VAC exactly the same way as with the original transformer. From the rectifier onwards the decks should be identical.

The only concern I have at the moment is with the 240V transformer, would all the other parts be compatible (by current, voltage, amperage, etc, etc), which were otherwise running off a 110V transformer, with this 240V transformer I need to change.
