I have an 892R radio transmitter tube (circa 1920’s and later) from a 12KW AM radio transmitter, they were used in both the modulator and power amplifier bays. This tube was operational when removed from the transmitter.
It is in perfect condition. The tube is approximately 24 inches tall and weighs in excess of 25 pounds. The base is solid finned copper. I am open to reasonable offers on this tube, it will be crated for shipping, or local pickup is possible.
Tried to attached photos but they didn’t take, email for pictures if interested.
