Item Description
This is a rare vacuum tube for audio of WE300B (made in April 1988) and WE310A (June 1980), which rarely appear! This is the one I have saved in my spare, I have listened to the two-stage amplified single like WE91 amplifier for another 30 years, but these guys do not break down, Emi reduction, it also It should be possible to use it in a movie theater in the United States for 50 years. This 300B has been aged for about 100 hours, 310A has reinforced the top grid with an adhesive, the single amplifier should be careful about the phase of OPT, check if OPT is for 2 or 3 stages, If it is three stages, transformer coupling is good instead of CR coupling, and it is good to connect SP system to the series even with monaural amplifier. Please enjoy the finest western sound.
