M4 amp是否应该变得更大

你好@Bdraudio
通常，当您更换电容时，您可以增加电压，这可能会更好，这取决于原始电压变坏的原因。
我已经看到电视机的实例，当从16V跳到25V时，由于电容器一直没有接近100％，所以增加了寿命。
至于改变电容值，我不建议除非有理由你需要改变它。
通常，如果您只是将要保持的部件更换为尽可能接近原件。
至于增加旁路电容，它可以帮助滤除电源噪声。
通常，您会在电源的VCC和GND之间找到一个，以帮助滤除电路中的噪声。
它还可以帮助传入尖峰。
我没有使用M4放大器，所以我不知道为什么人们会在你的确切实例中添加它们。

        Hello @Bdraudio
Generally when you are replacing caps you can increase the voltage and that can be better depending on why the original ones went bad. I have seen instances in TVs when jumping from a 16V to a 25V has increased the life as the caps are not running as close to 100% all the time.
As far as changing the capacitance value I would not recommend that unless there is a reason you are needing to change it. Generally if you are just replacing the part you want to keep as close to the original as possible.
As far as adding a bypass cap it can help with filtering noise from the power supply. Generally you would find one between the VCC and GND of your power supply to help filter noise into your circuit. It can also help with incoming spikes.
I have not worked with an M4 amp so I am not aware of why people are adding them in your exact instance.

好的是的，我理解你在帽子上说的关于不增加uf值的部分。
在放大器板上我自己同意尽可能保持它们。
现在这些是我正在采取的电源帽，我被告知uf的行为就像一个山谷，其中我加上更大声和更苛刻的负载如果我在uf值上稍微高一点它将大大填补在
山谷更好。
如果你得到类比。
我为旁路订购了2.2uf 250v Panasonic帽。
根据我的理解，它将有助于通过放大器滤波器保持噪声，因此我不会将放大器或电源噪声放入放大器的输出中。
现在这些功率上限是5个引脚上限，两个正2负和另一个引线。
我的问题是我在哪里解决了电路板底部的2.2uf电容。
从正面到负面到负面？
这就是我需要知道的。

        Ok yeah I understand the part you said on the caps about not increasing the uf value. On the amp board themselfs I agree about keeping them as close as possible. Now these are power supply cap I am taking about and I was told the uf acts like a valley wherein the louder and more demanding load I put on it If I go a little higher on the uf value it will substantially fill in the gaps in the valley better. If you get the analogy. And I ordered 2.2uf 250v Panasonic caps for the bypass. From what I understand it will help keep the noise down going through the amp filter it so I don’t get pops or power noise into the outputs of the amp kinda a filter at that. Now these power caps are a 5 lead cap two positive 2 negative and one other lead. My question is where do I solider the 2.2uf caps on the bottom of the board. Positive to positive negative to negative? That’s what I need to know.

我理解一个上限是如何运作的。
您遇到的问题是，盖子后面的电路是否可以处理较大盖帽的额外输入。
如果您正在过滤放入放大器的电源，您将在进入设备的正负线之间运行上限...

以下为原文

        I understand how a cap functions. The issue you run into is if the circuitry after the cap can handle the extra input from the larger cap.
If you are filtering the power supply coming into the amp you would be running the cap between the positive and negative line coming into the unit…

谢谢你所有的信息对我帮助很大。
是的，电源供电后的电路可以处理超过3000甚至雅马哈的人告诉我他说我可以走得更高，但我不应该超过22000uf，所以我在这方面是安全的。
他说，不要超过80v，他说80v是好的，因为75是原始的。
感谢所有的信息人真的很感激。
还有一个问题我现在知道对于旁路上限采取正面负面影响，但是对于上限为正或负是重要的是每个上限5导致两个pos和两个负？
或者我再次介入pos和negative之间



以下为原文

        Thank you for all the info helped me a lot. And yes the circuit after the power supply can handle 3000 more uf from what the guy at Yamaha told me he said I could go higher than that but I should not go past 22000uf so I am safe on that part. he stated that do not go above 80v he said 80v is fine being that 75 was original. Thanks for all the info guy really appreciate it. One more question now I know to go positive negative for the bypass caps but does it matter witch positive or negative on the caps there are two pos and two neg on each cap 5 lead? Or do I go between both pos and negative thanks again

您的正线应该连接起来并且负面连接因此无论您使用哪种都无关紧要。
如果您有双电容部件，例如启动/运行上限，则会出现例外情况。

以下为原文

        Your positive leads should be connected and negative would be connected so it would not matter which you are using.
The exception to this being if you had a dual capacitance part such as a start/run cap.
-Robert

得到了我还没有分开，或者我会看到哈哈。
我很高兴你们有这种形式，这对我来说是一个很大的帮助。
感谢您的时间，我知道它很有价值。

        Got ya I have not take apart yet or I would ha e seen that lol. I am glad you guys have this form it was a big help in learning for me. Thank you for your time I know it is valuable.
