question: If the grid circuit voltage is increased beyond its regular bias setting , what can happen to the conductive plates in power amplifiers ?
answer: cause the plates to glow red
turker_answer: If the grid circuit voltage is increased beyond its regular bias setting , it can cause the conductive plates in power amplifiers to glow red .
rule-based: If the grid circuit voltage is increased beyond its regular bias setting , cause the plates to glow red can happen to the conductive plates in power amplifiers .
