Hey Guys,
I've got this DBX F900a rack that has a power problem. Everything works great when I start the module up. After a couple of minutes all the leds start flashing, like there's not enough power to drive them. I've looked at the power supply unit, and I can tell that it has been worked on. The edge connector between the power supply and the main board is missing, and the power supply is connected directly to the main board using double wiring, I guess to cope with the high current flow. The other thing I notice is that the rectifier has been replaced with a KBL04, but from the schematics I can't tell if this is the right one (CRA1 FVLC266? or FULC288?). Now about the power transformer. The schematics show a 4 to 3 wire transformer, no output voltage stated. but mine has been replaced with an Arabel TK142-EK 150VA 2x18V 4,26A. Is this sufficient to get the +24V and -24V needed for the DBX modules? I have 6 DBX 905 EQ's, and 2 DBX 903 compressors that I would like to start using properly...
