    Mimiluna, have you checked the cartridge? It's crystal type and they loose their properties when they get older.

    Hello again from the sample which did establish that - transformer works well motora.No heard from the speaker hum (50 Hz)! And when you touch the needle - do not hear anything. Does anyone know what could be the problem?

    Check cables between the needle and amplifier. Maybe the amplifier is broken down?
    Here is the schematic: http://www.oldradio.pl/foto_schematy/sch00268.jpg
    Make sure that voltages and currents are similar with ones shown in the schematic. Try to touch the base of T101 with your finger - a loud noise should be audible.

    PS. Is your loudspeaker fully functional? Is it connected to the amplifier correctly?

    UF50 is a stereo catridge. You can connect it from DIN output into stereo amplifier.
    Pin 3 = channel L , pin 5 = channel R, pin 2 = GND.

    Hello! Thanks for all the advice. Discovered the problem - the cartridge not work and should therefore be replaced. On the one hand it is good that we found the problem, but on the other - now we can not find a new one. Does anyone know where I can find, order and buy?

    They are almost in continuous sale on allegro.pl (polish online auction site). You just have to find the seller who will agree send it abroad.
