Hey SC,
If you don't mind me asking, what's the reason?
I've been using 6L6 power tubes for years, and I feel the need to try something different, so this is why I went with the power amps I have now. I'm definitely getting a pronounced, and articulated bottom end response from these with a nice midrange, so I'm pretty happy with them.
No problem asking....
My preferred sound typology is Boogie Mk (IIC+, IV) which is mid heavy by itself. I tried it paired (Studio Preamp, Quad Preamp, Triaxis) with various EL34 power stages and it simply sounded meeeh. For my tastes it works best with either pure 6L6(W)GC, 5881 or in SimulClass mode (2:90, 295).
Since I don't gig out that often atm (mostly Madison Square bedroom and only some "Open Stage" events and maybe a hired hand job every 2-3months) I left the big WOMS in Germany in storage and only took the AxeFXII with me to Tokyo....(I nevertheless gave in to GAS and got myself a JP2C head).
Main aim for the Carvin Tube 100 now is ti pair it with the AxeFXII...and for that I wanna keep it as clean as possible, which is where the 6L6 excels over the EL34.
Well looking at the schematic you should be able to put 6L6's in it. Bias range goes to -57V so that should be enough for 6L6's.Heater current is less with 6L6's so that should be a problem either. Raa is a bit higher with 6L6's but not much so should be a problem either.
Thanks for that quick reply...I´ll give it a go once I've checked how it sounds with the EL34. Re-checking the schematic I couldn't find an Input 12AX7, just 2 PIs, correct?!
