You can get 5W at 2% THD maximum. I’d rather avoid filament bias at the output stage and instead apply fixed bias and a source follower driving the 4P1L stage. Best performance, lower THD at high output power. However, the above circuit is dead simple to implement without adding extra complexities!<\/p>\n
