I have recently completed converting an MLA-2500B to use the GI-7BT Triodes.
Thanks to a lot of hand holding by Lawson, W4EMF!
Now, I am building WD7S's great little TU-7B tuned input board to allow
driving the amp with a modern tranceiver which does not have an auto-tuner.
I am wondering how to determine the input impedance of these tubes. Plate
voltage is around 2300v. I have the data sheet, but am not seeing any
reference to the input impedance since this is a tube designed for pulsed
microwave service.
Any help would be much appreciated!
