Literally 5 minutes ago I finished my build of an Elenco XP-720K power supply kit. It has both DC +1.25 to 15V and DC -1.25 to 15V (1A), along with a DC +5V 3A output. And 12.6 VAC, for tubes I guess :-) $65 and 6 hours of work. No meters, nor current limiting, but hey, it's accurate and cheap. Manual is https://www.elenco.com/wp-content/uploads/2017/10/XP-720K_REV-J-2.pdf https://www.elenco.com/wp-content/uploads/2017/10/XP-720K_RE... Elenco also makes a pre-assembled version, but what's the fun in that?
