This is the main panel on the front of the Teac 3 Mixer

For the life of me I cannot remembr where this came from seems to be the main switching board so you can here monitor heaphones etc probably from an early M series as they used these switches

Removed from a working unit This was from the B16 but I am not certain if it would have neen used in other models as this was onlt the audio input output board and connctions to the heads

These are the two buttons at either side of the blue location meter

it has a 6MM shaft hole
