A Study of Telefunken Triode Type LD5

摘要

Photographs and radiographs were made of the tube in significant directions. Sets of curves were plotted on electrical data taken with the tube, and external dimensions were recorded. The internal parts were not measured, as only this tube was available. However the photographs and I-rays give a pretty clear indication of the construction. The X-rays also give information about sizes of the parts, since they are fu7ll-scale and will bear considerable magnification.
