JLM AC/DC troubleshooting
Posted: Wed Jun 06, 2007 9:37 pm
ok, I need a little help troubleshooting my busted AC/DC powersupply. By stupid mistake I messed up the power transformer wiring and some caps went poof Now that the caps are replaced the 48V section is fully functional, but the voltages at the V+ and V- just sit there at unregulated DC voltage (21V with 15V PT), the trimpots don't change the voltage. How can I find out what's broken? It's not the regulators, I already replaced one of them... thanks for any help!!
