Hello friends an fellow countrymen, I have a Presonus ACP88 compressor limiter with noise gates that melted the bridge, and transformer. I am trying to find a replacement transformer. Called Presonus and they left me on hold forever. It has a center taped three wire output, I assume it's 24 or better each leg, based on the input voltage of the caps, 50volt each 700uf. In fase or out? Any help?

Transformers rarely need replacing unless they plugged into wrong voltage (high) source. Still, a fuse should have opened. Transformers are dipped in varnish and often look damaged when they are fine. I have Presonus mixers but those all use switching power supplies. You can probably assume that the output of the regulators are around +/-15 volts and that the DC to the regulators will need to be about 20 volts for headroom. With a single diode drop assuming FWB with center tap, we need around a 15 volts either side of center transformer... you MIGHT get by with a 27 volt center tapped... probably not a 24 volt one. Recommendation... get an original one... In audio equipment the transformers often are specially designed to run low on the saturation curve or have magnetic shielding to avoid hum. If you call Presonus, DIRECTLY ask for "Parts" or "Repair Parts" else you are likely put on hold for sales or marketing.
