Was informed that using the resistance of a choke vs resistor in measuring voltage drop to calculate current is different. So I did the experiment on both channels. This tube has its own power supply. So across the 1st choke got 18ma. Across a resistor I got 16 ma. So the choke must be doing something to the DC which is over my head.
I guessing the resistor is the accurate one seeing that is how everyone seems to measure it but what is the choke doing to the get the different reading?
Thanks Tom
