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 shorted, but simply has low output. It would be ideal for testing an amplifier. - Only $19 plus shipping from Florida. - Thanks. 73, Ken Simpson, W8EK Voice Phone (352) 732-8400 .
