AM1780 help

[dcartledge]

Anyone have any dat on the AM 1780 amplifier?

I have all the correct cables, control boxes, headsets.

When I put power on the amp I got nothing. The power lamp would not come - no sign of life.

Is there a fuse inside there blown or am I just not operating it correctly....

If you have done every thing correct
Then may be one off the 3 relays is not working it is bad system.
But the military had many replacement parts we do not

Set the dial in the lower right to "Intercom Only" if you are powering the unit directly. Set it to "Other" if you are powering it from a radio.

At first I didn't realize that was a switch, I thought it was just a screw used to plug a hole in the case for and option mine didn't have.

the power relay will energize and click when it comes on, and check polarity
