|Heading:||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
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.
With 2400 volts on the plate, this one puts
out about 500 watts, which is just right for
this tube. In other words, it works as it should.
Buy this one for only $45.
This 4-250 has very low output, but it would
be very nice to use as a lamp. It is not shorted,
but simply has low output.
Buy both for $60.
Prices do not include shipping from Florida.
