I had a 55 Super 88, but I don't recall the speaker wire hookup. However, you can determine if one lead of the speaker voice coil is grounded to the speaker frame by using your ohmmeter on the R x 1 range.( Works best using analog needle gauge ohmmeter, rather than a digital type.) Touch one lead to the speaker wire connection, and the other to the speaker frame. If you hear a scratching sound from the speaker, then the voice coil is grounded to the speaker frame. That may be the way the factory did it. Perhaps the radio does work, but the speaker is simply bad. Try another speaker from a radio or small stereo, and hook the radio wire to one lead, and ground the other lead. I don't know what the nominal impedance of the speaker should be, but if you measure a resistance of at least 6 ohms across the speaker coil, it should be safe to use as a test speaker at low volume. Do all of your speaker ohmmeter testing with the radio wire disconnected. Obviously, the one thing you don't want to do is to hook the wire from the radio to a speaker terminal that is directly grounded . Other possible problems with your radio may be bad tubes, or a bad vibrator ( which was sort of a crude DC to AC converter.). If there's no buzzing sound , the vibrator may be at fault. Good luck !
