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 Voice Phone (352) 732-8400 .

These are NOS. - The 6CL6 is used as a driver tube in some of the hybrid rigs, plus many of the older vintage rigs.
