Leben CS 600 ( Dumper tube ) Tube rolling

I have done a fair amount of tube rolling in my beloved Leben CS 600 but have never attempted to roll the single dumper tube 6CJ3.  It did come with a vintage Sylvania tube.

I wonder has anyone ventured to roll it?

Does if have any effect on sound?  ( I am not sure why it would but wonder just the same).

I tried a few different ones. Didn’t notice any difference.

Different brands of rectifier tubes have a dramatic effect on Audio Note components. Their power supplies use tube regulation as well which also affects sonic signature. Don't know why it should.

So, I realized in my "box" of tubes, I did have a RCA NOS 6CJ3 hanging around.

I tried it in place of my stock Sylvania and did notice a difference in tone.  The RCA was in fact a touch warmer and more melodic.

Interesting for sure.  

I have procured a GE made Amperex ( for 10 dollars ) and will give it a try as well.

Thanks for your insights and happy Thanksgiving

I have a few of these sitting around if you want to buy them. Interesting that you find they make a difference.

Happy Thanksgiving!
