Ok now understand, 2.2V is the current trought the resistor so:
2.2V / 11R = 0.20A
And for 130mA:
2.2V / 16.5R = 0,13A
Yes, rough guide for projecting values. LEDs, Vgs, vary between parts and voltage levels wanted. If you measure your Vdrop across Rset on your own build you will calculate exactly on first test.
+-24V 100mA
For more than +-20V where is necessary to use the 1W rated resistors?
Wich is the voltage to match LEDs?
As I understand no matched 2SK170BL needed for mine setup, right?

The Vref set resistor drops enough voltage for 24V so it dissipates. Yes 1W.

Is possible to full populate the Hypnotize to use inside the Simplistic Phono RIAA to have in one box Phono pre-amp+Headphone amp or pre-amp/line-amp?
The Hypno has no gain of its own, so it can be in same box with a volume control if the power amp is about 0.5V sensitivity, because the simplistic is not a CD player. Most tube amplifiers can certainly be driven full.
Hmmm, I need gain mine Sennheiser have 300ohms, some easy idea to integrate gain inside the Simplistic or I have to post in the Simplistic thread?
No more gain for the Simplistic. Then THD will go up. Find a phones amp with 4-6X gain in the headphones threads or in general, if you want to integrate.
Don't worry I don't need more gain for Simplistic, the gain needed is for headphones, ok I will look for, any SS or tubes suggestion?
Mr. Gerhard has shown some good 5X one.

It's necessary to load both rails +-?, I have only loaded the rail + & the 3 leds both rails lit but the 5 leds rail - don't lit, the 2 leds togheter the test resistor lit & the two paralleled resistor 33ohms 1W are smoke go out.
It's possible that the problem is that leds don't lit are reversed & are being hot the resistors or that due to the fact that the rail - don't have load?
Please help.😕
