@JKDJedi I'm back in 6080 land. I got plugged in that Chatham 6080WA, and what a departure from the Sylvania JAN 6080WB I first had. No matter what I tried with the Sylvania, it just sounded muddy, bloated, just plain bad. The Chatham's got clarity, though sound stage seems slightly more narrow than the average 6AS7G....but makes the music more full bodied, its a tad on the darker side. I was running this power tube initially with a regular Tung Sol 6SN7GT and a Sylvania 7N7, which were a "just okay to good sounding". But the perfect pairing for me, I discovered is using it with a 6C8G. The properties of the high gain tube balances out and works swimmingly with this darker 6080. Hits the stride just right with this type of pairing. I am beginning to really think tung-sol/chatham's can do no wrong at this point.
