Same standard as Western Electric


Electrically equivalent to the original Western Electric historical tubes.

This tube can provide 140mA with a normal CLC filter. 274A and 274B are designed for audio applications, and their best use is as the first capacitor of small size.

The EML 274 is also particularly well suited for applications with relatively high DC voltages.The new ceramic sockets used in 2011 make this possible.

The intent of the 274B is to reduce the current peaks through the capacitors and power transformer.This results in less mechanical hum in the transformer, less electrical and magnetic hum radiation into the preamplifier, and improved sound compared to low-impedance rectifier tubes such as 5U4G or solid-state rectifiers.
