Hello all...
Sony HCD DX3....I am getting low volume on left channel. I checked amplifier board some capacitors bulged.(small caps)
I want to reCAP all amplifier board. Is it good Idea?
I can See Electrolytic , Ceramic , Mylar caps
can Mylar one replaced with Electrolytic?? help me with ur suggestions ..thank you
sorry for my bad English 🙁

The ceramic and mylar caps are unlikely to have deteriorated (unless subjected to overvoltage). Don't replace them with electrolytics.
Replace the faulty electrolytic caps first and see what happens.

Completely recapping an amplifier is almost always a bad idea.
First, fix what is faulty (probably some electrolytics in this case). Make sure the amp still works OK.
Second, replace things which are likely to fail in the near future or are known to have a short life (e.g. some PSU electrolytics). Make sure the amp still works OK.
Third (and this step is almost never needed, but is surprisingly popular), replace things where the original component was inappropriate - this assumes that you understand the circuit as well as the original designer and better than the original production engineer.
Fourth (this step is never needed, but is also popular), replace perfectly good working components with more expensive branded components which will be no better (in some cases if you pay enough money they will be worse!).
