Copied Replacement Circuit Board for Tube Holder
Replacement Circuit Board for Tube Holder
The quality of the electron beam in electron diffraction tube is affected by the resistance between sockets C5 (cathode) and F4 (heating filament) on the tube. For optimum results, the resistance needs to be 390 kOhm. Tube holder is accordingly designed such that this resistance is present. Older designs feature a much smaller resistance and need to be modified in order to work with the S-series electron deflection tube 1013889.
