TUBES - Amperex 4-250 Transmitting Tube For Sale


Amperex 4-250 Transmitting Tube For Sale:
-
The Amperex 4-250 / 5022 is a high power
transmitting tube, very closely related to
the well known 4-400, and a cousin to the
3-500. It fits the same socket as the 4-400
and 3-500.
-
The major difference between the 4-250 and
4-400 is that the 4-250 has 250 watts of plate
dissipation, while the 4-400 has 400 watts.
They usually can be used interchangeably as
long as the plate dissipation is not exceeded.
-
Weak 4-250
This 4-250 has low output.
It is not dead or shorted, but simply has low output.
It would be ideal for testing an amplifier. It is
NOT dead.
-
Only $19 plus shipping from Florida.
-
Thanks. 73,
Ken Simpson, W8EK
