I don't have any audio stuff that's point-to-point with no PCBs, but FWIW I've built some very pretty stuff with all the wires neatly bundled that oscillated and had hum issues. The same circuits with completely different layout, though much less appealing, worked great. I'm not saying there's anything wrong with beautiful layout and construction, just that it's no guarantee of maximizing the circuit performance. Some General Radio test equipment had really nice p2p work, and performed quite a bit better than good.
Luther is a member here, and is skilled in doing NASA-quality point to point wiring. His work will really give you something to shoot for.
Btw, the first dropdown is the build of a Bottlehead Foreplay. If you go down to the bottom of the page, the one with the vertical legs on the wooden case now belongs to yours truly, so I can personally vouch for the build quality.
Component placing (sockets, caps, etc) is critical to get a nice build like this. It takes a lot of forethought to get everything laid out without having long runs or having wire paths cross over each other too much.
I've never seen caps sitting on top of wire wound resistors like that. At least that's what it looks like in the bottom right quadrant of the pic where the blue electrolytic caps are sitting on top of the gold wire wounds.
I'm glad a leak has been shown. Those have impressed me with the tag board keeping all the components neat and the wiring around routed with military corners. I have seen some SS McIntosh with similar 90° turns in the wiring. Maybe they have some tube gear with this also. I searched for a leak and found this page. very neat wiring http://www.soundup.ru/index.php?opt...098:leak-tl12-1-amplifier&catid=10:amplifiers These make my Luxman tube amps look a bit rough. Even though the Luxmans have a couple boards the internal wiring is not bad. Since it does not qualify as point to point, you gotta click to see it. No reason to fill the thread with non-qualifying content.
