Voltage conversion gear question - Australian to USA

[Ugly Nora]

I have an Australian organ which is 240v as is my understanding what the mains electricity requirements in Australia is, and trying to use it in the USA with a step up/down converter shown below which is rated as the below:

Step Up: 110/117/120V AC to 220/230/240V AC
Step down from: 220/230/240V AC to 110/117/120V AC

When I plug it in and have the fuse set to 240V, I get no power. However, when I move the fuse to 110V, I get power but no sound. I am pretty certain it should be running at 240V, not 110V because that is how I run an English made delay pedal I run which works fine. Am I correct that this is the way I should be running it? And if so, why wouldn't I get any power that way, but I do running it at 110V?

Thanks

Yeah ac240V is the correct voltage rating to be running it at. Why the unit isn't powering though I'm not sure. Is there enough amperage in your step up/down transformer? If the transformer is variable, maybe try it at ac220V.

What's the organ and how old is it?
I've had old electric organs that were lass than reliable on sound output due to components drifting and drying out etc.

240v is right.
Try 230 or 220 as Kaos suggested but my money would be on faulty components of it's an older instrument.

Thanks for confirming team Australia. I don't know the exact age, probably 60s or 70s. It was allegedly confirmed working/serviced before being sent to me. I think it may have been damaged in shipping because there are other physical problems that weren't mentioned/shown in the pictures. Yes, I also tried 220V.

Thanks again.
