From Tube-Tech
The TUBE-TECH MEC1A Recording Channel is a classic channel strip, featuring a microphone preamplifier equalizer and compressor. At the heart of the shelving and bell filters you will find a tube operational amplifier.
The MEC 1A is all tube based except for the power supply. Input and Output have fully floating transformers. All DC voltages are stabilized, except the anode voltage for the output stage.
