1-07-1976 | This headphone arl;1plifi~r is intended for use with high impedance headphones (greater than 300 n) such as the Sennheiser HD414 and...

1-12-1975 | Using only two ICs, the TCA730 and TCA740, a complete stereo control amplifier can be built. An exceptional feature is that the volume,...

1-09-1975 | The Edwin amplifier is unusual in that it embodies two types of output stage in one amplifier. A class A output stage handles the low level...

1-09-1975 | "The input and driver stages Tl and T2 op erate as voltage am plifiers. The output stage, T3 and T4 , operates .in class B to achieve long b...

1-09-1975 | Amplification of signals at frequencies up to 30 MHz without di s tortion and with a level frequency response requires fairly complex circui...

1-07-1975 | When existing amplifiers lack sufficient input sensitivity and no space is avail- able inside their case, separate low power pre-amplifier...

1-07-1975 | Those who may find it fun, or even use- ful in some respect, can easily extend the single lamp stereo indication of an FM-receiver to give...

1-07-1975 | Transistors Tl and T2 form a voltage amplifier with a high input impedance and a low output impedance. When the # slider of preset pot...

1-07-1975 | Transistors TI and T2 form a direct- coupled voltage amplifier. Resistor R6 and diodes D l /D2 determine the quiesc- ent current of the qu...
