Conrad Johnson 17LS Owner. Will 6dj8 work?

Hi,
My Conrad-Johnson 17LS series I, comes with Sovtek 6922 tubes and I have some 6dj8 Amperex orange globes that I would like to try in my 17LS pre-amp but am not sure if I can cause any damage to either the tubes or the pre itself. I'm aware that in most cases 6922's and 7308's can be installed in place of 6dj8 circuits but I'm not sure the other way.
Thanks for any help.

6DJ8 (ECC88)
6922 (E88CC)
7308 (E188CC)

All work fine in Premier 16s and 17s. You can mix brands, but cannot mix types (ie., must be all 6DJ8, all 6922, etc.)

I agree Sanji, 6DJ8s sound sweetest, I like Amperex 6DJ8. 7308 is long life version (~10k hours). 7308 has a teeny bit more top end extension and better low-end articulation in my system, but not quite as sweet in the mids. Telefunkens are nice too; I could never prefer more than 1 Siemens 7308 per channel.
