Test published in the photo gallery read carefully below

As often happened during periods of overproduction Western Electric had a significant drop in quality control

This pair is part of one of these phases.

Probable last production before the re-edition, are presented as absolutely perfect in terms of aesthetics with none of the classic signs of wear, but to obtain the plate emission according to the data it is necessary to work on the negative grid tension.

As test attached this should be brought around -53 volts instead of the -58.5 volts recommended by data sheet. In this way the maximum emission (60mA) is obtained. It is true that in thirty years I have never found a sample that provided the full data of the data sheet.

Therefore: this pair, sold at a very special price, requires that the amplifier on which it will be installed allows to intervene on the grid tension. It is important that this is clear. DO NOT buy them making you seduce by the price if you are not able to make them work as indicated.
