- Bemerkung
- Photofact page 496-4 shows a 3-Input-Channel Push - Pull Audio Amplifier. The three input tubes are shown as 12SJ7 in the schematic but in the table for the voltage readings we find only two 12SJ7 plus a 6SJ7. Perhaps the entry of this tube shows 3 input sockets: One as a pair, the other on the other end of a potentiometer with an additional grunding in the "middle". There is no built-in speaker. Guest Gordon Waters from Marietta, USA, did write to us with the contact form that his set has in fact four inputs - in the way that reflects just the schematic: "There are two mic inputs, and TWO phono inputs- which are selected by turning the phono input knob all-the-way-left for one phono, and all-the-way right for the other (the input fades between the two phono, with the center being "off", or no signal from either).". He tells us too that the two 12SJ7 and the 6SJ7 are marked on the chassis. One can now see it both ways, a 3-Input-Channel Amp. or a 4-Input-Amp (with 3 channels). There is a speaker selector switch for 2, 2.7, 4, 8 and 500 Ohms.
