Amie, indeed you can get caught out, even with a ground plane. In my professional design work I've occasionally had to segment a ground plane to prevent circulating currents and induced noise. However it's nearly always a lot better than simple point-to-point wiring.
A conventional metal chassis, as commonly used for valve equipment, is a pretty good ground plane. In this respect, the move to PCBs, usually single sided in older domestic equipment, was a backwards step.
