just wanted to give a little update on this, I know i take a painfully long time to actually get any work done, or report back on it. but as ive mentioned (and/or made obvious) in other posts this is all a learning experience for me. which I do primarily as a hobby because I find it fascinating.
SO, to that end, ive learned how to read the little diagram on the boards for transistors, that has made it a lot easier to know which pin goes where.
so heres basically what has happened since my last post.
I had 8 transistors installed incorrectly, which blew 2 fuses (the ones from the orange wires of the transformer), ive put all transistors in the correct places, i triple checked that all transistors are the right ones for the spot, they were, they are all installed correctly, and my solder joints look good. so i replaced the fuses, put some cardboard inbetween the still loose amp board so the heatsink doesnt arc against the chassis, shook a little bit with nervousness, plugged it in and turned it on. the 2 or 3 seconds it takes feel like an eternity on the first power up. when i hear, click.
it comes out of protection now.
I still have to fix a wire that broke, one of the ones that go to the outputs broke, i guess spin that around the pin a bit and solder it on, that should be good right.
i have to start reassembling things, have to adjust the bias and offset, question on that, i dont see how i can adjust the offset without the outputs connected, but what about the bias? ive never done that before.
things are looking good so far though.
disclaimer: im working on this one for a friend who knows i take forever, but that i also dont charge;/
