T20IP Waterproof Transformer 8Ω to 100V Tapped to 20/10/5/2.5WThe T20IP is a small built in 100 volt line transformer, designed to make it possible to convert a standard 8 ohms loudspeaker into a 100 volt line speaker with selectable power taps (2. 5 5 10 and 20 watts in 100 volt). This transformer will open a lot of additional speaker models to the 100 volt speaker range. The only thing that needs to be done is to connect the T20IP transformer between the 100 volt amplifier and the low impedance loudspeaker.
