I would not use the GU-74 as a triode connected tetrode. It will not work.Craig

That's where I bought the last 3CXP800 drivers for a CCA broadcast tx a
year or so ago. The CXP version seems to give better life in FM service
than recent versions of the plain 3CX tubes. There might not be much
difference in HF usage between the CX and CXP versions as I recall the main
difference is that the CXP version will handle somewhat higher plate
voltage. Otherwise, they may just be a little better quality...
