Hi - I have a MkIVa from 1991. I know I can put EL34s in the outer sockets and run it in ClassA to get more of a Marshall-style output section, and I'm doing that now. I have EL34s in the outer sockets, and 5881s in the middle sockets, which seem (?) to have a slightly less powerful, more "vintagey" sound than the 6L6.
Can anyone tell me, does that seem accurate about the sound of the 5881 vs. the 6L6, or is it maybe just the specific tubes I have?
Also, and more importantly, is there anything dangerous about swapping the position of these tubes, ie, put the EL34s in the middle sockets, and the 5881s in the outer sockets, using Simulclass? I'm sure ClassA would be fine that way, but I'm not sure about having all four tubes on. But if I can do this, I can get the more "Fender" tone in ClassA, and add in the "Marshall" edge in Simulclass...
Thanks for the help!
