I was going to build a amplfyer from this instructable but had no BC548 or 2N3904 transistors. I did a google search to find out what could also work. I found a website stating simmalar transistors. On this website, at the related transistors section it states a few simmalar transistors. What transistors could I use instead of the BC548 or the 2N3904?
