Conrard-Johnson CT5 tube rolling?

c-j likes to say that you cannot find tubes that will make your preamp sound better than those they supply. Some people agree saying that the preamp will sound best with the tubes it was designed to use.

My experience with a c-j 17ls2 is that different tubes will change the sound of the preamp and I have found tubes that I prefer to the stock electro harmonix 6922s. This will not come as a shock to tube rollers.

I have not heard the CT5 but I don't think it would hurt to try some different good quality tubes and see what you think.

If you search some of the threads on tube rolling you will find the names of reputable tube sellers who can make recomendations based on what changes you would like to make to the CT5's sound.

Hi Vhiner, you are right, I don't think there is a substitute for the 6h30 other than the 6h30-DR which is a premium quality 6h30 that is no longer made.

They are for sale here on Audiogon for $280 a pair. I think it would be worth the investment to see how they work with your c-j. Considering what a CT5 costs it's a good idea to pay a little more for tubes that get the best out of it. I am not saying that you will like the 6h30-DR better though. I've never heard a CT5 with either tube.

Merry Christmas!
