I have a Berhinger ADA8000 that the mains transformer has burned out. Anybody knows where I can get a replacement? I read some threads and seems that it's a common problem with these units.
Logic is an organized way of going wrong with confidence
What's wrong with the transformer? Is it an open primary? If so, I believe this transformer has a center tapped primary for use with either 110V or 220V. You could try wiring the other half of the primary. It would only require moving one wire. This assumes you are in the US on 110-120V. If you updated your profile with your location, we'd know (hint).
Edit: Also check that something isn't shorted on the secondary before you fire it up again. If there is, you may just take out another transformer.

“Yeah, well, you know, that’s just, like, your opinion, man.”
This is a one-space rack thing, an Ultra-something. I was about to write some wrong stuff, then I found the drawing. There is a center tapped winding rectified and regulated to 15v rails with 7815/7915. From the same DC source there are also a pair of 7816/7916 ( I've never seen those) making what they call 17v rails.
There is a simple winding for +5. The raw DC feeds three separate 7805 Vregs. Three separate +5 rails.
There is a simple winding for +48. It is rather complex supply, but no doubling going on.
Pretty sure its a toroid.
Behringer schematics never include the transformer or mains wiring.
I have a couple other Behr rack items, but they do not have similar power supply. So I have no sacrificial parts.
Education is what you're left with after you have forgotten what you have learned.
Yes, it's a toroidal. I've found a new transformer for 39€. I think it is worth buying.
