Testing amp outside of tape machine

Hey there,

maybe someone here can help me. I need to test an ampex amplifier outside of the tape machine/frame. Im not good with tape machines at all and i just have to make certain that all cards work properly. Is there a way to test this on the bench? I guess id have to make some extra connections, but i dont know which ones:) At this point i get a healthy level on the vu meter when choosing the „input“ setting. A tiny signal on the „bias“ setting and nothing at all on the „repro“ setting. This is me simply feeding a sine wave to the xlr input. Any help is appreciated!
