The power tubes were spec’d by me so any other story or explanation is completely false. When we were testing the prototype (which is the amp I own) I settled on a pair of EL34s and a pair of 6CA7s. I dug the shit out of it like that at the time. In the 2 years or so since the amp came out I changed mine to a pair of 6L6s and a pair of 6CA7s. We all know how preferences change over time and we all use different tubes now and again. I very may well go back to the originals or may even try something else. Just as we all do from time to time...
Haven’t tried any 6550 or KT88s in it yet. I did realize that the bear traps were in the way of the large base tubes. That is a bummer and not something that I had an issue with during prototyping as I was only trying 6L6, 6CA7, and EL34 at that time.
The decision to add the Killer Kali channel was also mine. In fact just about every decision function wise by me. Mike is a rad dude and let me have my way with the design of the amp. It was a blast working on this.
I am running my 6L6s at 72mA and the 6CA7s at 68mA. I love it like that but you can run it hotter or colder to your tastes of course. Just follow the standard rules of biasing and you’ll be fine.
I honestly can not remember what the OG EP had in it when I first got it back in 2009. Yeah, it was that long ago…it currently has a pair of 6550s and a pair of 6L6s in it and it rips super hard.
My original Killer Kali++ has always had 6550s in it and still does to this day. I specifically did not want that on that amp.
