Golden Age Project COMP-3A 1 Channel Vintage Style CompressorThe COMP 3A is a one channel vintage style Compressor Leveler. The signal path uses only discrete components like resistors, capacitors and transistors. The input and output is transformer balanced, using two different transformers, each one optimized for its purpose. This is the way audio components were built before integrated circuits became available. The circuit used in the COMP 3A is based on a classic design that uses an electro luminescent
