hey-Hey!!!,
I had to smile at your screen wattage testing. I once ran 85W through the g2 of a 4E27 I was testing when I forgot to put B+ on the anode. It survived OK...
As to the differences, which data are the 100V/100 mA data comming from? I assume your measurements? I can't offer anything concrete, but a good sounding power pentode with a 60W plate is not going to get a very close look from me under most circumstances, eh?
cheers,
Douglas

It is quite obvious they simply posted 6550 curves to the El-156.
If you are going to pop in and get cocky, I could care less about your little 75 watt plate dissipation 4E27 tube. I have worked, professionally, with much mightier tubes than that pip squeak tube. How big do you want to go Doug?
The point is that the EL-156 tube is more rugged than the specs indicate, so the tube is run conservatively. Sometimes tubes get specs that they cannot meet without overloading.
Cheers.
