Never mind. I looked at the oscilloscope, and l looked at the schematic and decided that I should go ahead and do it. And when I did it I got a trace and a response to appear on channel b. So now I know that there is something wrong with the B attenuator. Now I need to look at the attenuator and see what is wrong.

What is the first place that I should start looking for issues? I think that it would be okay to start from the relays, which consist of a reed switch in a coil. What would be the best way test these?
