Roughly 2.2V/R gives the current as I say in post #1.
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
Oooops, looking for RCA connector for RIAA I get these nice caps suitables for C5 Shunt reg. PSU
BG WK Power Tank 220uF/200V, wow, can be suitables?
If they fit.

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.
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.![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
