The VA573 is a class A, all discrete, transformer balanced microphone preamplifier. It is based on the classic Neve 1073 module. The 573 also features an all new discrete high impedance D.I. that goes through the input transformer. The unit is also capable of accepting line level sources via a switch on the front panel.

This unit contains no IC's and no surface mount components. It is made at our shop here in the USA.
