Hello to all,
Im new in this forum. I recently acquired a Panasonic RF-1130 transistor radio. It is a nice tabletop radio with FM-AM-LW-SW bands and phono connection. It has a gyroscopic antenna and a kind of fine-tuning knob which works great in the SW bands.

The radio plays great with only one problem: there is a constant hiss coming out from the speaker immediately after the set is switched on, it does not change with volume and is constant, no matter where the band selector is. it is even there when I turn the radio to Phono mode.
I saw in other posts that this might be because of faulty resistors or transistor in the output stage.
Does anyone have the schematic of this radio on the basis of which i can check values of components?
If the problem is a transistor, can replacement transistors be found in electronics shops?
I am very experienced with tube radios, but this is my first solid state radio and I need some help!
