Re: Dynatron Jewel TP30 - first attempt at repair/restoration
It was standard practice on early PCBs to bend the component legs over before soldering. It would hold the components in place until they were soldered, either by hand or solder wave machine. Later you may find the leads have a sort of crimp spread instead done by a powered lead trimmer tool.
Modern SMD boards use a hot melt glue spot when the parts are placed. When the board goes through the oven, the glue softens and the surface tension of the solder together with the cunning layout of the solder pads pulls all the connections and the chip into perfect alignment.
