Jeff, 3-400Z tubes will work very well in a 6m amplifier. The only
precaution is try to test them before committing to all the work needed
to build a new amplifier.
If you plan ahead a bit, the amplifier could also accommodate a pair
of 3-500Z tubes.
Well wishes for a good outcome!
Wash the tubes, polish them up then take some good pictures, don't
forget the tripod. (And use as camera)

I have a pair of Eimac 3-400Z tubes. Would these tubes work well in a
grounded grid home brew amp for 6 meters SSB? I see the tube specs on a
3-400Z is for class B or C. Just asking for some input, thanks in advance.
