[Amps] GI-7BT Triodes

[K7ZS]

Thanks to all that answered with information to determine the input
impedance of my pair of GI-7BTs. I received a few direct answers to the
impedance,  and better still several methods to determine it through both
mathematics and real world measurements!

As a 'newbie' to amplifier building and repair, it is nice to know you will
not necessarily be ridiculed for asking a 'legitimate' or 'on-topic' but
possibly STUPID question on this reflector!!

Thanks, and Best 73
