Eddy.L said:Ok thank you ! I failed calculating the correct drop voltage resistor I have 6.3V to the lamp but don't have enough Ampers... But I know why.... And I don't understand how the drop resistor is related to the 6.3V that seems to be the output of the LM317 ? But I don't know if you have the time to explain me that.
I am sorry, but I am not sure what youre asking here, so Ill freestyle it.
IF you are drawing the connection from the 6.3V, you dont need a drop resistor to power a 6.3V LED package (You mentioned the desire to use such an LED in your previous post). You only need the drop resistor if you are drawing from the 9V secondary, which I would recommend.
You dont have enough amps, and you know why!? Could you rephrase this problem? I doubt you have a lack of available current, which is what it reads like..
If you answer the question "How are you trying to connect the LED?", it may clear it up
Eddy.L said:PS : last question... In the case that I bought there was already a switch with the IE Socket and I have wired it, is it a problem if wire a second switch at the primary thoroidal transformer ?
I dont see why, other than having two switches doing the same thing.
