Hand wiring a circuit can be as simple as placing components on the perfboard almost exactly as drawn in the schematic. For example, take the Hornet, my Fuzz Face clone:

Here is the schematic:

Here is the parts layout as placed on perfboard (you are looking through the perfboard as seen through the BOTTOM of the board):

Notice how similar they look? It is really true that if you connect the components together exactly as shown on a known good schematic and use the correct parts, the circuit will work. You can do this for a great many schematics. Simply place them on the perfboard almost exactly as drawn in the schematic. In the above example, the 100K trim connected to the .01uF cap has a lead that connects to the emitter of the 2nd transistor. Since it must not touch the emitter of the first transistor, simply run the wire on the TOP of the perfboard then run it back under to touch the transistor socket's lead.

Note that we are looking at the BOTTOM of the board as if the board was invisible and we could see right through it. As you build more and more projects, you will get used to looking at the board and the schematic and "visualizing" right through it. The leads that stick out of the bottom of the board will be your visual clues for placement.

The red dots are test points for setting up the trim pots. To set up a trim pot, you touch the black probe to a red dot on the trim and the red probe to the other point. Then turn the trim until you get close to the values shown on the schematic.

To test the transistor voltages at the collectors, connect the red probe to the red dot on the transistor socket and the black probe to ground.

More rough layouts

Take a look at these other rough layouts for perfboard. Basically you start from the schematic, rough sketch a layout on paper, then follow that layout on your perfboard. Don't forget that you can stand the resistors on end instead of having them flat on the perfboard. This saves a tremendous amount of space.

See how similar the perfboard layout can be to the schematic? Practice, and after a while, you will be able to layout and build a prototype perfboard circuit in very short time.
