RCA BA-6 Limiting Amplifier Broadcast Audio Equipment


⭕ This is a BA-6C, a late version of this model. The main difference from the earlier versions appear to be cosmetic. The C does not use the plug-in capacitors like the earlier model and is silver gray metallic rather than umber gray. It appears to be in amazingly good operating condition, as verified by our measurements.
