Review RCA 12au7wa Tube
The 6189-12AU7WA RCA 6189 12AU7WA Tube is a high-quality vacuum tube designed for use in various audio applications. This tube is a 12AU7WA, which is a type of triode vacuum tube that is commonly used in preamplifiers, audio power amplifiers, and other audio equipment.
The 6189-12AU7WA tube is made using high-quality materials and advanced manufacturing processes to ensure optimal performance. The tube has a glass envelope that is filled with a low-pressure gas, such as argon or nitrogen, which helps to maintain the electrical characteristics of the tube and prevent burnout. The tube also has a metal filament that heats up to produce the electrons that flow through the tube and generate an electrical signal.
The 6189-12AU7WA tube has a high gain and low distortion, making it ideal for use in preamplifiers. The tube also has a wide frequency response, which allows it to accurately reproduce audio signals across the entire audible spectrum. The tube also has a low noise floor, which means that it produces very little background noise, even at low volume levels.
The 6189-12AU7WA tube is a true vacuum tube, which means that it does not require any external power sources to operate. The tube is powered by the electrical signal that flows through it, and it generates its own electromagnetic field to amplify the signal. This allows the tube to produce a warm, rich sound that is often preferred over the sound produced by solid-state electronics.
The 6189-12AU7WA tube is a versatile tube that can be used in a wide range of audio equipment. It is compatible with both single-ended and push-pull amplifier circuits, and it can be used in both mono and stereo applications. The tube is also compatible with a wide range of power supplies, making it easy to integrate into existing audio systems.

Details:
Caveat: as indicated above, I have tested this tube and believe it is in the performance condition stated above. The two tirades are perfectly matched at 76 out of 100 scale readings. Both tirades readings dropped only 1 point 75 on the meter scale.
Tube must return in same condition as when shipped to you. Filament voltage s for each tried were reduced from 6. Tube tests: I have tested this along with 6 other 12au7 tubes and it tracks all of them for nominal test readings using an Eco model 625 tester. The printing on tube body have flaked off somewhat but 6189 12au7wa can be confirmed with a close look.
Used but test good versions are listed at up to 35.
With free shipping because of the condition printing on tube. However, the1959 Rca receiving tube manual, page 336 says: a tube-testing device can only indicate the difference between givens characteristics and those which are standard for that particular type. Based on this statement, I will accept a return of tube as follows: if you install used 6189 12au7 into circuit that is designed to and does not perform up standards, then the Dave - 56 novice.
It is designed for a long service life. Rca 12au7wa tube this is a pull from working Hammond communications receiver.
Here are its characteristics: cosmetics: the original 6189 number inside familiar Rca fence is really in good condition.
Give the reason for return at that time. Also, the printing on tube are Rca logo, manufacture code 69-04, Jr 6189 12au7wa. It is a rugged version of the regular 12au7 tube.
Life tests were performed on each tried in turn. The white printing has flaked off in places. I have marked this tube so that can identify it. Actual operating test in the equipment which tube is to be used will give best possible indication of as worth.
See pictures and the below. The tube tester, therefore, cannot be looked upon as a final authority in determining whether or not is always satisfactory. It is one of the most desirable versions this tube type and can be identified as such because has a full fetter burn on top envelope with clear body black plates.
