Yes, unless you have reason to question the performance. I would never change stuff just because I can. Once you get into changing the transistors, why stop there, as resistors especially carbon ones change value, and plastic connectors get brittle and can snap, then there's mechanical wear and.....and.....and.
It's rare for transistors to go bad.
That style of capacitor (FP) is not used for shielding. They are typically multi-section with a common negative terminal (the can). You can safely replace it with the same value of electrolytic with the same or higher voltage rating.
Thanks, but the part is definitely not multi-section, the three tabs around the circumference are all soldered to the ground plane in the power supply section of the board (I assume for physical stability, but thought there may be a shielding component there). There is only one terminal in the center which is the positive side. The capacitor is also only marked one value. It is marked:
This style of capacitor had various numbers of sections from one to four. Do a Google search on "FP style capacitor"
Interesting article. Perhaps explains the premature death of my Panasonic DMR-ES46V VHS-DVR combo deck. I opened it and about half of the Aluminum Electrolytics on the power supply/analog audio board were bulging or burst. Replaced all of the caps on that board and the deck lived to burn another DVD.
