Blow up his pic: his leads ("traces") appear to be straight felt pen lines to his pin-outs. . It's a good enough pic so when you blow it up you can see the leads to the pin-outs drawn clearly. It's rather cute. I think it one of the more concise ones I've seen. Unless I have it all wrong and the reverse much more overlap than the felt-tip pen lines.

Here's the bottom of the board. I forgot to put this pic on the page. I used a dremel to cut out the copper I didn't need, then I thickened the traces with solder. I then colored it with marker because I was bored. I designed the board on the fly as I always do. Somehow it usually works out.
Oh, that shiny stuff isn't flux, it's water. I used snow as a background for the last photo.

I'm very good with point to point, it's just a matter of finding a suitable base to keep it all steady. Point to point things just look so cool IMO, kind of like an art.

Well Myke, I don't want to be obsequious however let me say that I have used your model since I saw it! I just don't have the chops for what seems almost like "puzzle art". There were a great many things to consider in such a point to point size reduction.
I have a friend who actually does have some EE education (I have none) & I showed him (both pics of yours) & HE said "the guy is gifted" when I told him I was pirating the design. My old buddy was the guy who actually explained how the Mazelli functioned in it's relationship to both frequency alteration and why it was a better choice design than others I had played with. The first thing he noticed (in the design) was that the significant components were brought together with higher current in mind: short, thick, stout connections, etc. Muy' suave, senior.
Thinking this over realistically, all the people who have made quality examples of this driver started with a decent heat-sink. IMO - if a person can get a hold of a heat-sink that will hold both MOSFETS; the wiring CAN be simplified better and better the more you build them! Perhaps one of the nicest schematics are on Grenadier's site. extrapolating from that I think that if one were to build one with some fore-thought - that particular item may just be a serious help to making a unit that not only lasts and works well but is something to be proud of. One thing that has helped me was to put the schematic in a graphics program environment and shortening the traces. Certainly there are those folks that can build them right out of their head but if you're like me & don't have that gift......well - copying is the most sincerest form of flattery.
