The specifications for the 4-250A are the same as the 4-400A except for the plate dissipation. The 4-400A has fins added to the anode. I prefer the 4-250A tubes when I have an amplifier with a window. In SSB or CW a pair glows much better at full output power.

I've come across some of these tubes - are they useful as spares for any
commercial kit? Do they have any particular vices or virtues?

Thanks,
