Vacuum Tube 6BQ5 Hi-Fi TOSHIBA (Toshiba) MT9 pin 1 piece This item has been stored for a long time. It was tested in working equipment and then stored. The heater continuity was re-confirmed for this listing. There is some dirt on the exterior. Since it is made of glass, the dirt can be wiped off, but in the case of old vacuum tubes, the printing easily disappears, so I have not wiped it off. There is no original box. It will be wrapped in bubble wrap and shipped in a plastic case. #Vacuum tube #MT tube #6BQ5 Management number V029
