      LL79XX is the "NO COMPROMISE SERIES"
LL7901 LL7902 1+1+1+1 : 1+1+1+1 66x32x21  7901 is for low signal low impedance, LL7902 for high signal high impedance. Can do 1:1 1:2, 1:4
LL7903 1+1+1+1 : 2+2+2+2 66x32x21  Like 7901, but another windings ratio. Can do 1:2, 1:4 and 1:8
LL7904 1+1 : 1+1 66x32x21  High Level Splitting transformer. Also can be used as auto transformer for PP parafeed.
LL7905 1+1+1+1 : 
5.6 + 5.6		 66x32x21 

Less secondary windings, but aimed at higher windings ratio.
1) High level 600 ohms tube amplifier mic/line input (used 2 : 11.2) 
2) Can also be used as a (DC-free) line output transformer
