"The 25VCXP22 picture tube of my RCA Accutouch XL-100 CCU-942 TV start fading. Its 100% transistorized, everything still works perfectly after about 20 years service. But:
- Can I still buy new RCA 25VCXP22 picture tube? What is the approximate cost?
- Any equivalent tube for direct replacement? Cost?
- If no replacement picture tube is available, what is other option?"

What you have here is genericly referred to as the 25V as opposed to the 25A picture tube. While there are minor differences with respect to the letters after the V for the most part they are interchangeable. When I worked my way through engineering college I worked at a TV repair shop and my job was mostly changing picture tubes. Yeah, we did enough of them to keep a tech busy 4 to 5 hours a day changing them and I got pretty good and could change, color balance, convergence, etc. the tube in about 45 minutes. We for the most part used 3 major tubes, 1) 25A, 2) 25V, and 3) 21FJ (a little nostalgic for those who remember this one). This was back when your TV would have been fairly new (1981 to 82). These are available from many different sources - RCA, Channel Master, Wisconsin Tube, etc. The price would vary depending on the quality of the tube. I remember that we could get a 25A for about $35 at the time due to our volume - one truck per month. The most expensive I've seen them has been just over $200. This is quite a range and there are now many other types of tubes including in-line, trinitron, etc.
I hope this helps and thanks for the trip down memory lane!

The important thing here is that the tube begins with 25V. If it does it should work in your set. The only thing you have to know is whether the tube has 'ears' attached permanently. The 25V comes both with and without these mounting ears permanently attached. I know that you can still get one of these from any of a number of suppliers. I know that Channel Master and RCA (Thomson, whatever!) still make them available as well as any of a number of local CRT rebuilders.
