This is a set of vintage Universal Audio (UA / Urei) 1108 discrete transistor microphone preamplifiers with matching 508 passive equalizers. The preamps are transformer in and out and sound amazing. The EQs use passive capacitors and inductors for simple but smooth EQ. Restored and racked with phantom power and gain pots.
