You last sentence doesn't make sense?  |
I'm saying that you're partly right. By pulling more current out (via the choke) of the power supply, the voltage will drop. The choke doesn't drop voltage, it just demands the current that is needed and the changes in current demand are filtered by the choke. The dynamics of voltage sag with a choke vs a rectifier tube or reducing voltage filtering are not the same. That's what I'm saying.
A resistor is not a choke, its just a resistor.
You can still get some voltage sag with a choke but the dynamics of that sag are different when compared to sag that is due to lower power supply filtering, rectifier tube or a PT running at or over its limits. The sag will be tighter, if that makes any sense.
If you want sag, replace your filter caps to lower values like 32/32uf instead of 50/50uf
