Converting a 220v M3 amp to 110v?

post #1 of 7
Thread Starter 
Just wondering how readily an M3 amp built for use with 220v power outlets can be converted to 110v for use in the US?

How would one go about doing this?

Thanks

This is almost entirely dependent on what the power supply is. If it's a simple wallwart the conversion is simple, if it's a DIY power supply (like a STEPS) it may require more work. Bottom line the input to the M3 board is DC voltage regardless of the AC line voltage so nothing has to be changed on the amp side of things. More information required.

Yes, I had just realised this and was coming back to edit the original post. Its actually the external STEPS that takes 220V and needs to be converted.

If you're comfortable soldering the mod to the STEPS is not at all difficult. Read through Tangent's docs and you'll see it's just a matter of re-jumpering a portion of the board.

You'll need to buy a new transformer no? They're not cheap, $16 each.

Yep, the surgical way of doing it would be a new transformer with 110V primaries, and secondary windings the same as what is in there now... and you will have to double the fuse rating before the transformer...

The steps takes a dual 120v transformer as standard, and just by changing 2 jumpers it can be used with 120 or 240v, see the linked documentation from n_maher's post
