That cap appears to be the 3000 pF capacitor used to tune the primary of the transformer to resonance. If you can peak the slug on the primary then the cap is probably ok. If you still want to change it, you could try a 3000 pF silver mica.

Oscillation in the IF sounds more like a bad bypass cap in the screen or plate decoupling circuits.
