OK, I have made many standard DDL circuits and they hace all worked fine, even for the blu-rays. But I mostly just built them exactly as stated. Now I got a long open can from TheMonk and a Jayrob heatsink and want to crank up the current. So I thought by adding another 10 ohm resistor to the other 2 10 ohm resistors in parallel would raise the current significantly. But I can only get about 246 mA out of it. Now the only 10 ohm resistor I had left is 1/8th watt. Is the LM317 using more than 1/8th of a Watt to regulate? Does it actually pass the full current throug the adjusting resistor? Or just through the output?
Thanks
