I have it on good authority that later transmitters were equipped with the 
4CX250B, and that anyone re-tubing now should put in those instead of the 
glass-sealed 4x250B's.

The KWS-1 here is new enough that I have not opened it up to see what's in 
there, but the previous owner said it has 4CX250's in there.

Thanks to Kurt for his advice.
