What's everyone think of SMD? It seems more and more boutique builds are going that route, and with more parts only be available in SMD form, I wonder how long before it'll be hard to get quality parts in through-hole packages. All that to say, here's a simple etch-able SMD layout of the AMZ Mini Booster. I've left the power polarity diode and power filter cap (folded onto its side) as through-hole as getting the right packages can sometimes be a royal PITA. All the caps and resistors are 0805 size and note that C3 is a non-polarized cap. Should fit easily into a 1590A.
