Ok,
I'm bringing a DBX 900A rack unit back online. I have two of them, one is solid and working great, the other seems to have low 24v.
The power supply is supposed to give reg +/-15v & unreg +/-24v. The +/-24v seems to be around +/-16v and the +/-15v is around 14v.
DBX has a schemo posted online, but its fuzzy as heck and not much good, so I'm just kinda poking around.
It doesn't seem like much going on, a LM317 VR and TIP120/125 3055 type of setup.
