There's something that's been bothering me for a while. Many people and amp-kit companies advocate for proper lead dress meaning that you should make your wires both "as short as possible" and "tidy". And it seems that most of these kit companies, in their published pictures, have their wires almost always running along the chassis, and often bending at right angles. I never really understood this, because it seems like a contradiction to me. If you truly wanted your leads to be as short as possible, the you'd have to give up the right angles, as well as the wires running along the chassis, and instead connect them in a straight line in the 3rd dimension from one component to another. In addition, the advice for neatness also can go against the general advice to keep the wires separate from each other, when wires are bundled together and run along the chassis edge. Take a look at the Ceriatone image here, for example: https://www.flickr.com/photos/[email protected]/26343801374/in/album-72157665828886623/ For the twisted white wires running to the indicator light, it's definitely not as short as possible. They have it bending around the indicator, climbing up the wall of the chassis, and connecting to the indicator's terminals from behind. Same thing goes for the twisted purple wires running from the PT to the diodes. You could easily cut out half the length of that wire if you had it run directly, instead of bending around, hugging the chassis wall, before coming out at a right angle from the chassis wall and coming up to the diodes on the board. Same thing goes as well for the brown wires running from the PT to the heater of V5. And at the input jacks, the green wires running from the jacks to the board don't go directly there, they first run down to the chassis floor, then run along the floor, and then come up to the board. And we can see more on page 31 of the Metroamp instructions here: http://valvestorm.com/sites/default/files/50_WATT_KIT_INSTRUCTIONS.pdf The green heater wires going to V5 make this huge arc, coming at the tube pins perpendicularly. And the yellow wires coming from the 2nd can-cap make this right angle near the PT, instead of running directly toward the board. And if you take a look at the right edge, you can see that tons of wires are bundled together and run along the chassis wall. So I'm kinda wondering, what the guidance really is. Is it "keep your wires as short as possible, but this is not as important as having them neat and running at right angles to each other"? Or does it vary for different types of wires?
