After playing for a while, LM1875, I found that this IC is really good, the price is not high, the line is simple, the sound quality is good, the success rate is very high, it is difficult for so many friends to have a soft spot for him. But after reading the pictures sent by everyone, I found that many people bought the fake LM1875, and more people didn't know if the LM1875 was really real. So they went to the market and bought 3 fake LM1875s. Some true and false contrast pictures to show you, I hope more people do not be fooled.

Ok, let's take a look at this protagonist first, a total of 5 models, 3 true 2 fakes (there is a fake that I don't know where I was thrown after I came back, so only 2 fakes are left.

A - real goods, laser dark word straight leg version

B——True, old white straight leg version

C——True, old white bent leg version

D - fake, 2030 polished version

E - fake, laser dark word high imitation version

The so-called "bent legs, straight legs" is my own name, which corresponds to the two appearances in the factory PDF, except that the curved shape of the legs is different, the others are the same.

In particular, mention E in the picture, which is the high imitation version of the LM1875. This counterfeit 1875 is very similar. It looks almost the same from the front. If there is no contrast, it is difficult to see the problem.
