CJ PV-14L replacement tubes

What is the tube compliment for that unit?

No big deal as long as you don;t need to bias the tubes. If small signal tubes you can do it yourself. Just make sure to use same type tube in that position. I have a VTL 5.5 which i have cover off and tube role onece in a while, i leave top off. Like you said just wiggle out tube and reset it in tight. Make sure pins are in exact place. What type tubes does it take? I have some you may need.

Why don't you pull the tubes and let us know what kind they are, then we could offer suggestions.

All I could find on the tubes used in the CJ 14L preamp are that it has 2 valves. V1 and V2 and both are 8080s. I can't say that I have much familiarity with 8080s so I will leave it for those that do. I think I also read that these are called 6C4s. Good luck my only comment is that factory tubes are very very expensive and I personally can't see the difference between buying from a knowledgeable and careful dealer who screens out bad tubes and the factory.

Thanks for all the responses - very helpful. I believe they are 6C4 tubes as mentioned. Next rookie question - where can I buy them if not through CJ?
Thanks.
