Vacuum tube 6BQ7A HITACHI MT9 pin 1 piece This item has been stored for a long time. I have confirmed heater continuity for this listing. There is some dirt on the exterior. Since it is made of glass, it can be wiped off, but the printing on old vacuum tubes can easily disappear, so I have not wiped it. No original box. It will be wrapped in bubble wrap and shipped in a plastic case. #Vacuum tube #MT tube #6BQ7A Management number V030
