How a resistor and cap will sense a tube demand. This is well below the 84 that runs fine and also much lower than the 72 that starts to glow red. The Linlai tube data says the tube has a plate current of 64 at 1000 volts. I was told these will redplate in my amp.
I also have a set of C that have a plate current of 70. My C tube data says the same, but the plate current is 84. It is a mild discolor of black plate to faint opaque red. IF this is the case, why is it that some tubes redplate and others don't. In some ways auto biasing is a bit like plug and play and takes away a lot of the setting up issues of fixed bias setups. So basically if your tube is looking for 65mA that what the auto biasing will give it, HT voltage does not change however at 960-980V. For example too much bias current and it’s turned down automatically and too little bias current and it’s turned up automatically. The auto cathode biasing, bias voltage varies up and down automatically to keep the correct bias based on the tube.
Yet I am told the following about the autobios. I have some tubes in my stash that will redplate.
