Description
This lot contains 2 large vintage vacuum tubes of differing sizes for electronics. The larger of the vacuum tubes is an Eimac 4-400C/6675 Radial Beam Power Tetrode. This vacuum tube was used in broadcast equipment such as RF power amplifiers, and was rated at a maximum of 400-Watts. Examples of this vacuum tube could be had for around $600 dollars online. The second vacuum tube is of an unknown make, but of similar construction to the 4-400C. This vacuum tube may have also been used for broadcast / amplification equipment. The smaller vacuum tube measures approximately 2.5” in diameter and 5.5” tall. The Eimac 4-400C measures approximately 3.25” in diameter and 6” tall. Both vacuum tubes appear to be in good condition.
