Pre-73 DLX MKII Tantalum capacitors in the signal

Tantalum capacitors in the signal path

The D2 MKII has a flat response with a mild lift in the upper midrange

Carnhill input transformer

This filter is active in about the same frequency range as the presence peak and therefore lowers it when it is engaged

Pre-73 DLX MKII Tantalum capacitors in the signalThe PRE 73 DLX MKII is a one channel vintage style microphone , line and instrument preamplifier. The signal path uses only discrete components like resistors, capacitors and transistors. The line and microphone input and the line output are transformer balanced, using three different transformers, each one optimized for its purpose. This is the way audio components were built before integrated circuits became available. The subjective sound quality
