AMPEX MM1200 UNI-RELAY RETROFIT PCB
The TONECRAFT UNI-RELAY PCB is our DIY friendly solution for retrofitting the AMPEX MM1200 Tape Machine with modern, readily available relays. New relays will drastically improve the functionality and reliability of your machine. Each channel of your machine will require 3 of these relays for the switcher board. We are selling the PCB only. This is a mid-skill level DIY project. Additional parts are required to complete each board including relays, pins, connector and shunts and may be purchased separately from common vendors such as Mouser and Digikey. We include a detailed bill of materials with part numbers and vendor details along with assembly instructions.
