Nutone model 2500 multi pin connectors

The chassis of the 2500 is made up of many steel panels, which are all screwed together.  On the rear of the 2500 there are 3 multi-pin connectors which are for power, speaker and transformer connections.

NuTone provided Service Centers with a special power adapter kit, which could be used to power up the 2500 when it was being service on the workbench.  Without this kit, it would be necessary to remove the power transformer form the wall housing and use it as the power source.
