A 16GP4 is a 70 degree tube. I would be interested in a 16AP4 which is a 50 degree tube.
Do they have any shells? Otherwise I have a couple of duds.
Question: the HV (EHT) of the late 40's sets using a 16AP4 is only 10 to 12 kV. Will the aluminized screen be as bright? Perhaps brighter?
Thanks,
Terry
