LENCO A 300 Schematic?

[roger-k]

A frend of mine have a amplifier: LENCO-ITALIA A 300.
R87 and R88 are burned, and I do not know the value of these resistors.
I hope anybody can help me to find the values of the resistors.
Thanks.

This schematics is hard to find...
If you post a photo of PCB & PTH perhaps it can possible to
calculate the value.

To calculate the values I need to draw the schematic, and that is very much work.

I have search on internet in many hours and you are right:
This schematic is very hard to find.

Hi, 😀

Also the schematics can be to draw form PCB & PTH
If the circuit is enough simple. 🙄

Hi Roger-K;

I have the same amplifier to repair.

Can you tell me the name of the transistor Q1 Q2 Q3 and Q4? thanks

R87 and R88 are 5,6 ohm.

Do you have find schematic of this amplifier? thanks and good work

Sorry for my bad english, but i'm Italian and don't speak english very well...😀
