Woah! I hadn't seen the YC156 curves before, and I have to doff my hat to
the people brave enough to run them -- if, that is, the data for the plate
current curves at/above 20 Amps weren't extrapolated. 9.9 KV at 110 Amps,
plate-to-cathode, is pretty heavy duty; I suspect it took a fast hand on
the switch and some chart recorders.

The area interesting to us hams (the ones who stay legal, anyway) sure
doesn't use much of that sheet. 

Thanks, Jim, and very 73.
