Ok, the parts I ordered from Solen came today and I have a few questions. First, the inductors, are they coated in anything that I need to strip off before I solder them? If so, what do I use to remove the coating? If not, can I just solder them using the same solder that I plan on using to solder the resistors and caps? Also, the inductors came with some length of wire out of wind with the rest of the inductor, does it matter if I just cut this wire to the minimum length I need to solder (after I solder naturally)? Next question. I ordered metal oxide resistors, are they polarized? If so, which end is which? Last question. I need perf boards, large ones. This is my very first DIY speaker project and I've never soldered anything other than a couple cheep radioshack resistors before. I need a large (and strong, these parts are heavy) board to place all the parts on. I'd still like to keep the cost down but what's the largest I can get and where do I find it? Thanks!
