[QUOTE="fredeb, post: 1043529, member: 13623"] If I understand the OP's enquiry , it is whether music is playing or not and the amp is on in both scenarios . Yes, don't leave the amp on when you're not listening , the valves will wear down from just being on , but not playing music . Other than that , biasing of output tubes , or small signal tubes ,could possibly make them wear down faster if running hot . I personally like biasing output tubes at about 70% of max dissipation , which help the output tubes last longer . [/QUOTE]
