Sorry, was cut off from the internet.
If you remember what we were talking about..
Sorry no.
:-/ Oh, how complicated the world is.
when there is lots of current there is only a small voltage across the transistor
Finally, I've measured this, and it appeares to be true.
If you use a FET
I've read about them before starting building schemes, and it seemed quite remarkable thing to me, but when I saw other people's things made with transistors, they all were using usual bipolar transistor, I don't know why.
By the way, I bought a new transistor, a more powerful one (120 W), but it becomes hot all the same.
What would you do in my shoes? I've heard about some heat sinks, may be this is the way to go..?
Thanks a lot.
