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.
-

6CL6 tubes For Sale: 6CL6 tubes For Sale:
-
I found a stash of 6CL6 tubes. These are NOS.
-
The 6CL6 is used as a driver tube in some of the
hybrid rigs, plus many of the older vintage rigs.
Many have found that low power output in these
rigs is due to a weak 6CL6 instead of weak finals.
-
Buy these for only $8 each, plus shipping from Florida.
