Rare DeForest 424 A-C Screen Grid Amplifier Tube. 1929. The tube appears to be NIB so we chose to not unwrap it for a photo. The original box is in great shape with only one missing flap. The condition of the tube itself is 100% unknown. It has not been unwrapped or tested in any way. There are no warranties expressed or implied given that the tube is 95 years old! The tube and box will be bagged and carefully packed in a USPS medium flat rate box with a copious amount of bubble wrap. If you have any questions, please let us know.
