Western Electric 274 Type Inductors

Normally when you need to use Western Electric filter choke in your amplifier,
first type of WE inductor that you think about was an expensive 241 type inductor.

241 type are very nice inductors and support high current rating in some models.
Use in famous WE amplifiers like 118A, etc.

But if you need to use for lower current rating circuit like preamplifier 
or low power amplifier, you can use 274 type inductors with lower cost too.  


Combination with 307 type inductor too.


Aluminium enclosure with engraved model & date codes.



Also has screened version.


Assemble with only 2 screws.


Raw information but can guide when you see on somewhere.
