I`d like to Doug explain it, but I`ll try. It probably means that it isn`t "normal" signal (only of very HF) present on the input grid and amplified. It can be "extreme" and so "high" that the stage "overloads" (grid current). Sound still can "pass through", but "weak, undynamic, distorted, glassy..."
Everything can oscillate, no matter class of work, or device used - but high gm parts more likely. Even anode-stopper (between the CCS and anode, say 100 Ohms) isn`t over the top measure...
