Hi friends I’ve been working on amphi for a long time and I wanted to share it with you, I hope this will guide most people, this is a jeep amp named Lm3875.
It is a great deal more overseas fans of the Circuit, Turkey also very much an unknown integrate Why does not a circuit I say should though be sold in Turkey, but the integration of a brother, the LM3886 Turkey has also plentiful, far as I know with lm3875 and LM3886 Class A-ab with working class , LM3886 before, one of the differences between the two circuitry between the simplicity of the other in the LM3886 bass in the foreground and a more powerful and LM3875, bass and other details are balanced in balanced.
I have integrated lm3875 from abroad, I made a circuit quite simple and plain ( flat ), so any pre-amplifier, buffer, no tone control circuit can say that in this state affected me.
The circuit box etc. I used the aluminum parts as an amphitheater, I’m going to do it soon, I’ll try the copper for the class a amp, I’m going to do a classic bridge-type rectifier, I put a coil to get more linear tension to the supply capacitors. ” pi ” filters.
I did not have heat problems in the circuit as I have used in the photos, I used a large refrigerant, but as far as I remember, the lm3886 and 3875 integrated thermal, dc-ac short circuit protection features such as.
So far I have recommended that you do not try any of the applications such as lm4780,3886,3875 friends easy come to everyone
LM3875 was a 56-watt amplifier chip made by Texas Instruments (previously National Semiconductor). It was very popular in the DIY audio community for its low parts count and its high-performance audio capabilities. It was the main chip inside many gain clone amplifiers which are based on the Gain card amplifier.
