DIYRE 73P Module - Fully Built and Tested

The 73P is an authentic, complete adaptation of the vintage 1073®* mic preamp circuitry to the 500-series format. The 73P is authentic in that it uses only components that are hand-selected to match the original, and there are no changes to any of the preamp circuitry. The 73P is complete in that it adheres to the original, three-stage amplifier design.

Module fully hand-built and tested by Siegfried Meier of Beach Road Electronics.  Made to order!  Please email for availability.
