You said you had someone to do maintenance on that thing. I'd set it up for you if I were able to travel. Maybe someday....
In the meantime, I can only give you some advice.
The speaker wires each have two separate wires in them. Make sure the two wires in each line aren't touching each other where they're connected to the speaker or the back of the receiver. If they touch, the line is shorted out, and there won't be any sound in that channel.
Also make sure the plastic insulation on the speaker wires isn't broken, as that'll also short the two wires together.
If you have more than one pair of speakers connected to the receiver, disconnect all but one left speaker and one right speaker. While those old receivers can nominally handle two speakers per channel, each additional pair reduces the impedance load per channel. That can cause too much current draw and fry either the speakers or the receiver.
Finally, each pair of wires has a polarity. The positive (+) terminal on the receiver should be connected to the positive terminal on the speaker. Same with the negative (-) terminals. If they're backwards, one speaker will be out of phase with the other, which would definitely cancel out some of the sounds in the recording.
