Re: EM84 tube - pinout and spec?
Thanks Paul, interesting.
From the datasheet then iI see iI need to give it 6.3v on the heater and +250v DC on anode, but between o and -10v ish on the grid?
OK, so the 250v should be easy enough, and the heater volts, since iI have the transformer out of the radio, but how to generate the negative LT for testing the function on the grid? Perhaps just an extra battery to provide that?
Does anyone have a simple test circuit?
