AudioSector LM3875

Posted 12th August 2013 at 10:55 AM by MagnumOpus

My first completed build. I used an Alps in a box for this one before I finished my awesome B1.

It's a tight fit, and I get some noise from the toroid, but it's hardly audible and not at all when the music is playing.

Takman Resistors, Toroidy transformer, DH Labs and Kimber hookup, Connex RCA's. Its not the most powerfull amp, but it drives my PSB Image B6 just fine and then some. The most awesome sound I have ever had in my own house, and I actually don't miss a thing. I would put it in a bigger chassis and perhaps get some copper to further shield the toroid instead of building another amp.

But I have pcb's for a Zen v9, so that's it

    You could try to route the input/output cabling on only one side of the transformer. That way the toroid would not be enclosed by the wiring. Going from the attached picture, I would route everything to the right of the transformer.
