Hey all,
I've made a 317/337 based power supply to power a pair of 500 modules. It has worked fine until I came across one brand of module that doesnt work. The Vintage Design m581mk2 module is having issues with the supply. Vintage design states they have a " power on delay to prevent PSU errors". From what I see, they have a 7824 regulator that ups the 16v supplied to 24 for their DOA.
Also, they have I think a pair of relays that turn off the voltage rails if it doesnt like what it sees. So when you engage one of the lighted push switches on the front, it turns on and off and on and off and I hear the relay firing. Right now I'm just trying to power 1 module. In the past I have powered a single great river two wide module, and pairs of avedis ma5, shadow hills mono gamas, and others without issue.
Soooo, is the lm317 too weak to power such a setup? Does a fixed voltage regulator have more ooomph available? Help!
