hi guys i have to do a project for school .I have to design a pcb layout after a schematic . I found an 50 W amplifier but i do not know what is LF356 used for in this case .Which is its role in the schematic?.If you know what is all about tell me please.
thanks a lot
all the best!

The output signal come from the output of STK through the feedback network R3/R4. The AC voltage gain is R3/R4+1=22.5
The output signal also come via R14 to the noninverting integrator LF356,R13,R14,C14,C15. That integrator (DC servo) helps to maintain zero DC level at the output of STK.
You can find more info about STK here:

dimitri thanks for your answer.I also want to ask you if you can give me a scematic of an old russian schematic or an echivalent one.I had an 1991 production year audio station but the final PCB were so hard dammaged that i had to threw them away.I was an 50-80 W amplifier(i do nor remember the production code) which worked on KT818 and KT819 complementarliy disposed.I steel have the power transistors the toroid transformer the aluminium heaters and i vould like to use them .It was suplied by +-37 V.I want to ask you if you do not have such a schematic
thanks
