*pics* parallel gainclone finished

this is an inverting gainclone, using parallel LM3875's with a 250va 22-0-22 transformer.. and sounds wonderful

the music is effortless the bass is smoother and more "defined" (for lack of a better word) than a single LM3886/channel.

Hey, what a coincidence, I just bought a couple pairs of those heatsinks from a local surplus store (prolly same place, princess?).
Nice work bud. Got a schem?

it looks alot more complicated and more advanced than it is.... it's a vinal sticker I got made a few years ago.. I applied it to the metal before painting.. then I just painted over it.. gives a nice raised look..
* ya I got the heatsinks at pricess auto.. they work great for the gainclone.. was tricky to adapt to the wholes that were already there though.

Yeah, I don't mind the corner holes, but the holes in the middle of the sink turned me off, I bought few anyway. The heatsinks look very good in your application, looks very professional.

What schematic did you use?

Just the app note one?

your paint looks like raw aluminum to me... what paint did you use?
