This amplifier consists of two transistor stages T1, T2, which are fed by any source of DC voltage B between the terminals +3 and -B with the shown Polarity anjele ^ t is «The output of T2 (collector) feeds the excitation pulses from relay RH, which, in addition to contact 12, which closes the supply circuit of EL3, is equipped with a further working contact 13, which is connected to the tapping point of a capacitor C4- In the quiescent state, ie. when RH is de-energized, contact 13 closes a terminal of C4- to the -B pole of a G-line supply line B (while the other terminal of Oa is constantly connected to +3) and thereby becomes C4 charged to the voltage of the green current supply line B (for example -12 VoIt) ₄ If, on the other hand, the relay RLI is excited by a signal arriving at the amplifier input AE1, the contact 13 connects the negative terminal v on C4 with one end of the resistor R6, whose. other end is connected to the base of T1 so that the

T1 is applied, the relay RL1 is energized after a closing delay of 1-2 seconds (which is determined by the damping of the R1, Gi-'jliedes) and accordingly its contact 12 is closed, whereby the electromagnet EL3 is energized picking up the small phone MT. 3-at the same time the contact 13 is closed, which, as said, releases one of the pads 04 from -B and connects the same to the base of the transistor T1 via R6. The voltage from 04 is then applied to the input of T1 so that it remains conductive for a certain time (depending on the time constant R6-C4), even after the input signal has stopped, so there !? also RL1 remains excited during this sack since. The values of R6 and 04 are chosen so that, for example, a time constant of approx. 15-20 seconds is obtained. It should be noted, however, that since a minimum negative voltage at the base of T1 is sufficient to keep amplifier AK1 conducting, the side during which r RL1 remains energized will be greater than the time constant R6-C4, and can for example be 3–4 times longer (namely about 30-40 seconds, and even more). As a result, does the arousal before? RH through the repeater AK1 said that the telephone?
