Been away from the forum for a little while but I'm back and thinking about building an amp. I recently received some old electronic odds and ends that got me thinking... One of which is an old working eiko 460 oscilloscope. So I was thinking maybe I could use the transformer from that for a build. And maybe even the case and knobs as it's pretty sweet. So how does one determine the merits of a found transformer and whether it will work? The only thing I see on it are the numbers 30015-3, 9967025. I really don't have a preference of what to build yet, but was thinking something well documented like a 5f1, 5e3, etc. Probably build it as a head. I will probably get a partial kit like from Boot hill and mix an match stuff that I have if possible to make it my own I'd love to build something AC flavoured but realize that might out of the realm just yet. Preferably something smaller for at home playing and recording as that's all I do.
