Subject: [Amps] Led display problem
Hi All,
I'm new on this list...
I'm planning to build a 2m amp with a 4CX1500B tetrode.
I want it a bit state of the art and replace the meters with LED bars.
My design will be a cathode driven, DC grounded amplifier and i want to
monitor at least screen, grid and anode current and anode voltage.
The LM3914 input seems to be always referenced to ground. No problem to
measure the screen current for which a pole of the supply is grounded.
But a bit more difficult to measure the other currents and voltages for
which the reference et the cathode level.
Has anyone an idea how to do that, on a simple way ?
73, Patrick TK5EP.
