I prefer to drive them with around 20-25w carrier, but 40 is max.
Peak or ssb input should not exceed 300w, 150-200 is preferrable.

The pep drive would be ssb or AM.
I wouldn't want to run much over a 300w AM carrier, maybe 400 max. Usually 20w carrier in gives 300w carrier out, might be the tubes are a little soft.
