Hii attmci, You are referring to my single TS5998 that I since acquired a mate for. When you are looking for bargains, patience is a virtue. I am waiting for a real deal on the GEC 6080, but so far no luck. Will keep trying.... Here is something wild that I just thought of (may be cringe-worthy to some): Since the current draw of the Euforia/Elise is the sum total of all the tubes, how about a pair of 6BL7 or 6BX7 as drivers with 1.2A power tubes such as the EL12N? Or the other way around... The total current draw is 5.4 which is well within the capacity of the 7A of the Euforia (or 6.8A of the Elise). When I muster up enough courage I am going to try it... And here is another candidate for the uncrowded field of top power tubes: The EL6. Yes, I know that they are rare, but ATM I am using a pair with a pair of 6SN7GTB as drivers, and the results are excellent.
