Thank you, and yes, it is a "G." From the etching on the glass it is clear, but earlier I was reading handwriting. It did feed voltage immediately, as I have about 30 VAC feeding as I type. The B+ is around 15 vdc and climbing. I will tune in again after either full voltage or some catastrophe ends the power-up. Thanks for the explanation of the difference in these tubes.
Full power-up has been a success and B+ was measured at 420 vdc. Thanks to all for the help.
