Thanks for the help!
I will buy a resistor and give it a try then!

 

Alright then! I googled power resistors and every single one available seems to have a very smal restiatance value (0.01-2.20 ohm). Why is this? I want a resistance value of around 88 ohm. Is there some kind of relation between the resistance of power resistors and regular resistors?

 

Use a capacitor to drop the voltage without heat, it needs to drop 120v @ 136mA, thats appx 3.6uF non polarised cap @ 450V


Xc = 880 ohms

The resistor values are somewhat limited for power resistors.
Here's an 82 ohm 3W that should work, for example.

If you want to use a capacitor to drop directly from the 220V then you need to drop about 140V to also solve his over-drive problem (which would be closer to 2μF for a resistive load).

But you need to be concerned that the series capacitor doesn't resonate with the trimmer inductance and actually increases the current rather than reduces it.
