DustDye Posted November 2, 2018 Share Posted November 2, 2018 (edited) Hello guys, I just bought one of these (HD350) and it's on the way to my place. Got it from a US user, so it's set to operate at 120V with the proper fuse inside. Do you know if I should make any adjustments to the amp for a 220V operation other than replacing the fuse? I read some advice here and there but nothing solid.. Some say that it's a class H amp, and I don't know if it's relevant, but also hope I don't have to replace the whole power supply section.. Thanks for the help! Edited November 2, 2018 by DustDye Quote Link to comment Share on other sites More sharing options...
Skybone Posted November 2, 2018 Share Posted November 2, 2018 Or you could get a step down transformer from a builders merchants. Quote Link to comment Share on other sites More sharing options...
DustDye Posted November 2, 2018 Author Share Posted November 2, 2018 Yeah, EBS guys told me I should replace the power section Quote Link to comment Share on other sites More sharing options...

But if you have been in touch with EBS they would have told you that. It is a US spec 120v model so either a step-down transformer or replace the power section. It could just be a board swap but I bet it won't be cheap. I guess with the amount of amps around now with switch mode power supplies, it is easy to think that any amp will work anywhere as switch mode ones do.

DustDye Posted November 2, 2018 Author Share Posted November 2, 2018 I hoped so.. but they say the parts themselves aren't pricey. Let's see how much a local tech charges for this. Quote Link to comment Share on other sites More sharing options...
DustDye Posted November 13, 2018 Author Share Posted November 13, 2018 (edited) So this was a really quick fix. Got the amp, got the toroid transformer and new fuses from EBS. Everything is connected with jumpers so it's just taking the old transformer out, putting the new one in. (If anyone needs a US 120V transformer for the HD350... :)) Edited November 13, 2018 by DustDye Quote Link to comment Share on other sites More sharing options...
BassBunny Posted November 13, 2018 Share Posted November 13, 2018 Excellent result and big up to EBS for the design. Quote Link to comment Share on other sites More sharing options...
