3-400Zs and 3-500Zs have the same peak cathode emission and the same anode-V rating. For RTTY service, he 3-500Z has an advantage. For SSB, it doesn't. I noticed the amplification factor for the 3-400Z is 200 where it is 130 or less for the 3-500Z and 3-500ZG tubes. thanks.......... 3-400Zs are slightly easier to drive. Richard L.
