I got a hold of a an Instek GPS-3030 power supply for 5 bucks. There's a problem with the output. I've tracked down an issue where a 15 volt regulator and a TIP32C transistor are overheating, so there's probably a short somewhere. I'm wondering if anybody would be able to help find a service manual for me, or a schematic of the board. I've scoured google for the past day or so looking for one, but still came up zip. This particular power supply also goes under the models Protek - 305L (analog dial) and the Tenma 72-2010. Thanks!
