Looking for tubes 6CL8 pentode Triode with lower output ratings

[713]

Hi:

I originally posted this thread on CAM but didnt have many replies.

The ones I have for my pre amp are 6cl8 tubes.

My pre is like this one that recently sold.

I want less output from the tubes as all the 6cl8 types I own have a great deal of gain.

Direct replacements are 5cl8, 9cl8 and 6cl6.

Unfortunately they are not the most refined tubes but the prices are very reasonable.

It would be nice to throw a couple handsome looking 6dj8`s in there but I know I cant do that.

Is there a general output specification i can be looking for?

Will different manufacturers have slightly different outputs as well?

Are there any other tubes you guys can think of that would produce less gain with my Pre?

I dont have a schematic and my DIY knowledge is somewhat limited hence the reason for this query.

Thanks.

Are you using the phono stage, or just the CD input?

I searched for substitutes, but came up empty. It's an interesting implementation of a pretty unique tube, but not much good if you're into tube rolling.

Thanks for your reply.

I am using the phono stage 95% of the time and love my vinyl.

The tape inputs use a line stage which bypasses the cd and phono tube section.

Hello!
I know it's late my answer...do you still own that preamp?
I am very curious about the schematic or service manual, I ordered such tubes and have no project for them yet....but they seem very interesting tubes....maybe with the tetrode wired as triode.

Does anyone have some application ot the tube above?
