Very nice & clean looking Dynahi you got there!

Those heatsinks do look a little small though, have you had any problems with overheating? The heatsinks on mine are quite a bit larger, but they still overheat after 5+ hours & cause a little distortion.

So far I haven't had any problems (knocking on wood). I haven't had it on for more than an hour and a half continuously though. The case is pretty big and has decent ventilation so hopefully that helps.

Heres my latest addition. If you cant recognize it off the bat, the circuit is based on the 4556 OP amp and runs off two 9v batteries. The resistors are all Vishay/dale metal films, pot is a (somewhat)cheapo Alpha 100k. Which seems pretty good for me. No need for a 40 dollar pot in this amp! 5.1uf Solens, Bulgin battery drawers which makes it SO much easier to change the batteries than with my old amp. Neutik jack etc.. Im pretty happy with the performance, extremely quiet. No trace of noise even at full volume.

The wood i used is african mahogany, which i just put a couple of coats of polyurethane on. Came out georgeous (the wood). The copper top and bottom covers along with the fascia and rear peices were originally going to be aluminum but i didnt have any that wasnt scratched beyond repair. I built it a bit bigger than i had to because i like the idea of a real clean open layout. Measures 8" wide by 10" deep by only an inch and 3/4 tall.

I also added a white LED on the bottom under the volume control since i didnt have any real logical place to put it on the front. But it shines off whatever the amp is sitting on so it lets you know, Hey! Im on! Even with the LED, while the amp is playing music the total current draw is only 11ma. I built this one pretty much from scratch. Designed and Etched the PCB myself. Actually the artwork is my old design, i have a new one now which is less than half the size.

THE PICS!

Wow... The case is totally beautiful, and the layout of the stuff inside is really neat.

Cool - we'll all just make up our own reasons for why.

The first of three identical set of boards of Diamond buffering as seen in the PPAv2 for the PIMETA:

n1342260049_30000802_8337.jpg


n1342260049_30000804_9460.jpg


I used cheapo 22AWG speaker wire I had lying around, as I ran out of normal wire, and 18AWG normal wire was WAY too thick to use. I have not tested this board out yet. I will test it out when I finish the two remaining boards.

I would like to thank Tangent for helping me out in shrinking board sizes. Bottom board is 1.1 inches by 0.8 inches. Top board is 0.9 inches by 0.8 inches.
