[Hallicrafters] 5k matching transformer - 100v Line transformers

I have this table that relates to a 100v audio line transformer...

Secondary is 8 Ohms

Primary 20k       0.5 Watt tapping
        10k       1.0 Watt tapping 
         5k       2.0 Watt tapping
       2.5k       5.0 Watt tapping

I don't have a listing for a 4 Ohm output, the transformer you find may have both a 4 and an 8 Ohm
output, that would make it easier to work out.
