Referring to the Rider schematic, I would replace capacitors numbered 22, 23 and 24. The 370 pf caps usually have drifted and cause difficulty setting the pushbuttons and also may cause drift during warmup. The 250 pf cap was bad in a restoration that I did a while back. The oscillator was stopping intermittently.
Kind regards,
Terry
