Audio note 300b amplifier11/8/2023 ![]() ![]() The TRV-A300SE integrated amplifier uses one 6SN7 driver followed by a 300B power triode per channel. Our own Audio Meishu is a long way from stock so judging the effects of tube rolling was better done on the unmodified Tri. Its Japanese designer used a very simple single-ended circuit, point to point soldering and good quality components throughout. As an integrated amplifier built by the book, the TRV-A300SE presented the perfect opportunity. The idea of doing a tube comparison evolved during our review of the Tri TRV-A300SE for the Dutch Music Emotion magazine syndicated on 6moons here. It is no wonder we call our stash of available tubes the spice rack. What other electronic part can make such a difference in the way we experience music and is swapped so easily? Sure, cables can alter the perceived musical reproduction but they are not the most convenient flavoring of sound. Tube rolling is a joy forever and that ain't no lie.
