Rectifier Tube WESTERN ELECTRIC 422A
This is the WESTERN ELECTRIC 422A, a renowned rectifier tube alongside the 274B.
The downside is that the center guide pin is missing.
It's difficult to see in the image, but there is a mark of a convex part remaining when viewed from below, at the 12 o'clock position. If you align this convex part with the concave key in the socket, it can be used correctly. (It will be clearer upon physical inspection.)
The upside is that there is plenty of getter remaining, and the pins are clean, making it appear close to new.
It was tested in a Type 91 power amplifier.
It was swapped with a 274B.
The sound quality and resolution are not inferior. For vocals, the s sounds are not harsh, and the 422A feels more natural.
Fortunately, it has 8 pins, so it is also stable.
Due to the nature of the product, please no claims, no returns. It will be shipped with careful packaging.
