THESE AUTOTRANSFORMERS USE ONLY A SINGLE TAPPED WINDING AND ALLOW IMPEDANCES RANGING FROM 4 OHMS TO 600 OHMS TO BE MATCHED WITH MINIMAL LOSS. THERE ARE ACTUALLY TWO IDENTICAL WINDING ON EACH UNIT. IN USE ONE WOULD CONNECT LIKE COLOR WIRES TOGETHER PUTTING THE TWO WINDINGS IN PARALLEL FOR CORRECT MATCHING TYPICAL USE WOULD BE TO MATCH A LOW IMPEDANCE AMPLIFIER (4 OHMS) TO AN 8 OHM SPEAKER OR 600 OHMS TO A CONSTANT VOLTAGE 70 VOLT LINE (ASSUMING 10 WATTS PWR). THE TRANSFORMER WILL HANDLE TO 25 WATTS. THESE TRANSFORMER WERE MANUFACTURED BY MERIT TRANSFORMERS AND WERE DESIGNED TO MATCH A 15 WATT AUDIO MONITOR AMPLIFIER TO VARIOUS LOADS. THESE TRANSFORMERS WERE DESIGNED TO BE MOUNTED IN A ONE RACK UNIT (1-3/4") CHASIS (SEE PHOTO OF TYPICAL INSTALLATION). THE TRANSFORMERS WERE DESIGNED AND MADE VERY CONSERVATIVE.
