The cathode resistor failure is common. When the resistor opens, the dc on the cathode rises to plate level and destroys the cap.
The plate resistors in the PI? That seems unrelated. I would expect the 1k in the ps to blow first. Maybe it was oscillating at a high frequency and overtaxed them. It's a headscratcher.
