Hi guys, I recently got a Peavey 6534+ and sounds amazing with an od in front, just need to get my zilla fatboy 2x12 up and I'm sorted one thing I have been considering is changing the tubes, I've been looking up kt77 and kt88s, I know the kt77's will fit in place of the EL34s but not sure about the KT88s. I've heard that some marshalls can accommodate KT88s and was just wondering if some people had tried fitting kt88's in this amp? Thanks
