If the 80 is missing (4 pins on bottom of tube) the good news is that you probably did not hurt anything turning it on. The bad news is - it will not work with the 80 missing it is the rectifier for the high voltage - no high voltage - no work. If there are 2 42s in push pull it will work with one missing.

Where are you located?
