Conway, There is space to solder them. Solder at about the height of the top of the RPaks, and clip the leads off just above that point so the KSB2 option will fit. Hole the soldering iron tip so that is lots of contact with the crystal case to maximize the heat transfer. The solder does not

Don, The issue is that the ground leads on the left side of the case is between a resistor pack and the crystal case. There isn't the room to solder the ground lead after soldering the crystal in place. Should I solder the ground leads onto the case BEFORE I solder the crystal onto the PC board?

Conway, Use a hot soldering iron - 800 deg F - to heat the crystal cases quickly. Use a flat bladed screwdriver to form the ground leads up against the crystal case. Then apply the soldering iron (out a bit of solder on the iron tip to aid heat transfer). Hold the solder on the crystal can

What is the best way to solder X7-X11 crystals? The instructions say to solder two ground leads on the side. The ground leads on the left are between the crystal and the resistor packs. I think I should solder the ground leads onto the crystals before soldering the leads onto the crystal case (a
