Greg,
Before you apply loop voltage it is a good idea to first adjust the
Line Adjust pot to maximum resistance (should be CCW) to keep
excessive current from blowing the fuse or possibly damaging the
meter or the selector magnets. Normally a suitable value power
resistor should be inserted in the series loop to limit current if
the pot is accidently turned up near max. Also the fuses should be
checked to be sure they are the correct value.
If the tuning forks are missing the speed can be checked by holding
down the space bar and counting the number of spaces in a measured
amount of time. For 60 words per minute it should be 60 spaces in 10 seconds.
