Ratio 5:1. 15k/600 Ohms output transformer for driving balanced line from AC coupled cathode follower or SRPP circuit. Total DC resistance referred to secondary 31 Ohms. Max output level +30 dBu. 30% Mumetal core. Similar to UTC A24 and Triad HS-50 (in overall 5:1 configuration) but with improved bandwidth. Suitable for PCB. Also suitable for UE-100 output. This transformer is very similar to type 1010 and is essentially a size and cost reduced version achieved by using a smaller lamination size and a smaller proportion of Mumetal laminations. The can size is also smaller and less expensive. The performance is unaffected except at very high level low frequencies where the THD measures somewhat higher.
