My chipamp

[zymurgn]

Hi guys, I just wanted to share my project with you. I originally posted this as a reply to another thread, but I thought it would be more visible as its own post.

I used the 1875 kit from Chipamp.com

I hope you guys like it!

Nice! You can't get much simpler than that.

Are you only using one of the heatsinks?

[bego2]

niccceee...very nice box, where did you get it? how much?

nice work...you have two heatsinks, why use one ?

[zymurgn]

I like the design of both ICs on the same heatsink, everything fits better. Aside from that, it is large enough be more than enough to dissipate the heat under full load. In other versions I might change it up though.

Don't you see? The whole box is a heatsink.

[zymurgn]

Exactly!

There's nothing wrong with that. My dual LM1875 amp (that I built about 15 years ago) has both chips on a 3"x1"x1" heatsink. I don't often drive it that hard, but when I do it doesn't get too hot. With moderate listening levels it is barely warm to the touch.

I am in the process of building this kit. May I ask what transformer you used?

[zymurgn]

The toroid is an Avel Lindburg 160VA
Model # Y236502

Good Luck with the project!

I am planning to use the XFM-D0012 toroidal transformer 21.5 Volts at 2.7 amps from Apex Junior for the LM1875 Gainclone Kit from BrianGT. On one side it has red,white,blue and black wires. On the other side it has orange, red ,brown and black wires.

Can someone please advise me the correct way to wire these to the kits power supply PCB and the mains connection?
