Got a pre-owned pair of EL34 Telefunken single O getter black base paired with 6C5s.. Warm and detailed sound of EL34 but a bit dryer than the Tesla...
Good match with T1 using high output (8 Ohms tap)...

Listening Maggie Reilly best of with T1 . (for the one remembering Mike Oldfield in the 80's ) and then Mike Oldfield - Return to Ommadawn..

Anyone with blues and EL34? I think I might have something for you.

I listen to this using 2 different setup. Oblivion > He1000se and Destiny > LCD4. Both just as good. Against this backdrop I'll be evaluating Odyssey.

EL34 is an important power tube for me. EL12 spez is a predecessor of it and have similar DNA.

Cycling to the same tubes, I keep only EL34 as output and roll different 6J5 and my only pair of 6N7. all sound good, but I start to think I might need to get a pair of EL3N->6J5 and EL11->6J5 adapters. We will see, I think I'll need to expand a little bit my army of inputs.

Strapped pentodes as triodes gives off a different pleasing sound that is vivid and punchy. Such as EL3N, EL11 and c3g. Go ahead try it. As for me, I have EL11 and I can't wait to use that in a custom setup.

I've sold my Siemens C3g with Elise, but I still have a pair of Valvo EL11 and 3 pairs of Philips EL3N. So, why not, I'll think about it. I'll have to break my rule of "no adapter is best adapter" and this requires judgement and decision. :)

I think I can, I tried EL3N with a dual adapter EL3N -> 6SN7 and worked well, but the adapter broke, was a chinese stuff, if I'll try those again I'll use some single adapters to 6J5.
