Tubes for a Conrad Johnson 17LS?


I just purchased a (used) CR 17LS Pre. This is not the 17LS2 version. I haven't got it home yet, but I'm already wondering if there's some experience out there with 6922 tubes. Also, are there other tube types that will work in this unit that are not 6922s? Thank you in advance, for your time!

Dopogue,

Should there be any concern with mixing 7308s with E88CCs (which I believe are 6922s) because of different electrical characteristics? The fact that you're doing this without any issues would obviously seem to indicate that there isn't any problem but thought I'd ask. I had read in a few other places that it wouldn't be a good idea to mix types (6DJ8s with 6922s, 6DJ8s with 7308s or 6922s with 7308s) because they are each somewhat different. Although mixing brands (Siemens, Amperex, etc.) of the same type would be okay and could lead to synergistic results.

Thanks,
Joe
