The Amperex UY89 Rectifier Tube, Hickok, is a vintage electronic component that holds a significant place in the history of audio technology. This tubes is a 6CA7 equivalent, a type of rectifier tube, and is known for its robust performance and reliability.
The Amperex UY89 is a high-voltage rectifier tube, designed to convert alternating current (AC) into direct current (DC) efficiently. It operates on a high voltage of around 400V and delivers a current of 1 ampere, making it suitable for applications requiring high power and voltage handling capabilities.
The tube is housed in a glass envelope, which is vacuum-sealed to prevent the internal gases from reacting with the air. The filament is made of tungsten, which heats up to produce the necessary electrons for conduction. The tube's plate, also made of tungsten, acts as the anode and cathode, respectively, during the rectification process.
The Amperex UY89 tube is a popular choice among audio enthusiasts and collectors due to its warm, tubeless sound. It is often used in vintage audio equipment, such as amplifiers, radio receivers, and hi-fi systems, to produce a rich, full-bodied sound.
In summary, the Amperex UY89 Rectifier Tube, Hickok, is a high-voltage, high-current tube that is known for its reliability, robust performance, and vintage sound quality. It is a must-have for audio enthusiasts and collectors who appreciate the unique sound and character of vintage electronics.

These are wonderful sites full of PDF specifications vacuum tubes, we get our data from them.
Special thanks to frank Philips whose web site is tube data.
Some of our tubes come with original boxes.
If a used or nos tube is on the lower end of manufacturers range we discount price.
Hickok 539c provides a minimum acceptable mutual conductance. Since we open all boxes to test them, sometimes the box flaps or tabs are damaged and will note this in of tube.
Our supply of tubes: we buy all tubes from reliable sources and are always on the look out for quality tube suppliers. This is a test where the filament voltage reduced by 10, which gives an indication of future performance tube.
You can be sure that when we say a base is loose, it only slightly loose and used as-is.
Every tube, whether used, nos new old stock, or nib in box is tested for shorts using our hickok 539c ohm-meter. All tubes are gas leak tested to ensure the reliable performance of tube. If a used, nos or nib tube is packed in new standard white box, the box will have tubes test results on its label.
