Planet Audio PL3000.1D Capacitor questions
It is easy to spot and replace bad components, especially blown capacitors. It is harder to answer the question “why” to the owner at times when it’s just a capacitor failure.
This Planet Audio 3000.1D is another fine example of this situation. The capacitors are obviously bad, with not a single sign of overheating anywhere else in the amp and no bad input or output transistors. All the fixative is normal which typically you can tell when it gets cooked.
So while this is in waiting for capacitors to arrive I want to gain more of an understanding to answer the “why” question because it will be asked.

Is this ripple current, ESR change from internal heating, power supply sag or Undervoltage yet no other component failure or signs of stress. The thermal paste is not hardened.
Maybe bad capacitors? The paper that blew out is dry as there is no electrolyte? These are 63v 1000uf YUSCON TM low ESR series
Thank you for your input!
