So you are using something like a 6.8 Ohm series resistor on each side of the heater to get these figures?
If you use a series resistor on each side, what effect does that result in on the DC-bias, none or something that you have to adjust for? Do you short these resistors after some time so they are not affecting the circuit, or do you leave them in there? /Martin On Tuesday, 30 June 2020 21:03:50 UTC+2, gregebert wrote: > > Be careful about the inrush current when energizing the filaments; the > cold resistance is around 2.8 ohms, whereas hot is around 7 ohms.
