Is the copper strip with the resistors on it just hanging in the air in front of the transistors supported only by all the wires connected to it, or is it touching the transistors or even attached to them (glued perhaps)?

In terms of copying the circuit in the photo of John's SG, any suggestions/tips about the order/manner in which to attach the different components?
