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

[Ed Tanton]

Hi Folks... I have the good fortune to have a multi-tapped transformer with 
0 > 4, 0 > 8, and 0 >16 ohm taps; with the following taps on the other side:

All are referenced to "0":

30W = 165 ohm
25W = 200 ohm
20W = 250 ohm
10W = 500 ohm
   5W = 1000 ohm
2.5W= 2000 ohm

There is also a 45 ohm tap that is not marked with a 'wattage'. I suspect 
this is a 70V transformer, but do not know for sure.
