I have landed on Telefunken ECC88/6DJ8's. They are all that the BB's convey with a bit more bass punch. Very nice for some not so exotic tubes, ie: gold pin, JAN, CCa or e88cc variety. This is all very dependent on not just the T8+, but on the rest of the front end as well as the amps. But if you want tubes that fit under the hood I hope you'll try some of what I've been able to try and report back on.

Enjoy!
