Chipper
The chipping hammer is a hammer-like tool and is used to find mechanical defects in electron tubes as well as loose contacts and cold soldering points in electronic assemblies .
The head of this tool has a soft rubber part and - because of the usually life-threatening high voltages in the tube circuits used at the time - a shaft made of insulating material . With this tool you can z. B. gently tap the tube in question to inspect it for any defects. In this way, internal short circuits between two electrodes (“cracks”) or loose contacts (mostly due to broken welds ) can be detected. If a defective tube was found, the service technician would replace it with a new one from the “tube case” that was previously essential.
Since electron tubes are rarely used, this previously indispensable tool lost its importance. In specialist shops, however, it is still available together with other tools in tool assortments (or individually). In the hobby area, a wooden pencil or a screwdriver is often used as an inexpensive replacement, with the latter taking hold of the blade and tapping the tube with the handle.
