I ineterprete TL431 as a zener diode--but the diode giving us
flexible breakdown voltages inbetween 2.5V and max 36V
depending on the resistor values arranged between K, Ref and A pins.

That's about right It's a "shunt regulator" . A refrence, an op amp and a pass transistor. It turns on and off the pass transistor to maintain the programed voltage. Probably about 8.5V or so???

One thing though. the terms Cathode and Anode? wouldn't they be + and - respectively???

Cathode is (-) and Anode is (+).

why I have impression that Papa must be giggle now.............

edit:

any toob boy in panty hoses know that anode is on more positive pole,cathode is on more negative pole, and grid is more than often going south.................


I see that entire DIYa is predestined for massive harakiri............

cviller - you are just as bad as Steenoe (building stuff so fast), but even worse - I just picked up 12"x12" copper clad board today to etch your babelfish layout and now you are teasing us with F4 layout ...

Of course, you will have to let us know how it sounds
