| APPLICATION For driving a balanced or unbalanced audio line from a single ended pre amplifier. Ideal for HiFi pre amplifier or for studio microphone or distribution amplifier. Best low frequency performance is obtained when driven from a low impedance source (Valve with a low plate resistance, rp) but 10Hz 3 dB point possible with a 3K source. When terminated with a 600 ohm load the reflected anode load is 8.5K. Reflected load may be adjusted by adjusting the load resistance. | ||||||
| FEATURES A very large core to ensure a high bandwidth and low output impedance. High grade grain oriented silicon iron (M6) core for minimal losses and harmonic distortion. Multi section winding ensures minimal leakage inductance for an exceptional bandwidth. Low copper resistance which permits an output impedance of 203 ohms when driven from a valve with rp = 3000 ohms and a secondary load of 600 ohms. | ||||||
