Stax SRM-500t Tube Driver Unit for Stax Earspeakers Avon4 it has been engineered toSTAX introduces a new vacuum tube output driver unit SRM 500T, the successor model of SRM 006tS. STAX custom made low noise DUAL FET is installed on First Stage and the vacuum tube6FQ7 6CG7 is installed on Output Stage. STAX continued to use the traditional circuit design which is perfect for STAX vacuum tube driver and improved the power efficiency. Finally SRM 500T achieved the sound quality improvement. In addition to the conventional power
