I have a glass that was made for a 1980 (the faceplate should have real glass installed, not plastic) a while back that never got used. While you can likely have a piece made by your local glass shop for $20, the one I have is tempered, and damned unlikely to break. If you're interested, email me.
At any rate, you can measure the offset by looking at pins 3 and 6 of the power supply board (yellow and green wire). Anything over about 2V will prevent the relay from engaging. But...while you are there, you need to check the remainder of the PS voltages. The Achilles heel of the 1980 is that power supply board, mounted up under the bottom of the chassis where it bakes itself to death. 19 out of 20 failures on the 1980 are due to a failure of one of the +/-80V supplies.
