Aretha-LT-n

Designed with the audio enthusiast in mind, Aretha LT is a single ended 6SL7 based preamplifier. The circuit is a cathode follower with Baxandall tone controls, all housed in a custom wood chassis.

The power supplies are regulated solid state DC, powered by a Lundahl transformer custom made for Erhard Audio.

Coupling capacitors are Mundorf MCap EVO's, signal path resistors are Vishay and TE Connectivity high precision film types.

The printed circuit boards are designed in house, manufactured to FR4-TG standards, and are double-layer with ground planes on both sides to ensure proper screening of the circuits.

RCA sockets are gold plated and mounted directly onto their dedicated printed circuit board, which also carries the selector switch which is connected via a stainless steel shaft, supported by a miniature ball bearing running through the front panel to the selector knob.

The volume control is a precision machined 59 step attenuator, -60dB to 0dB.
