Mark IV EL34/6V6 questions and advice needed.....

[mdortona]

Need some more input from you guys. I have a Mark IV combo that I'm testing out and so far, I'm liking it better than my Roadster for most applications. FWIW, I'm running it through a 1-12 3/4 back cab (without the combo's internal speaker).

Sound-wise, with the EL-34/6L6 combination, what can/should I expect on the three channels? Would there be any major differences other than a reduced overall output if we went with 4 6V6s instead of 4 6L6s?

Unfortunately, I don't have the disposable cash to do real live tube tests right now and certainly don't want to do anything to risk damaging the amp, since I most likely will return it to where I purchased it (I want a widebody Mark IV head).

Thanks again!

I see the biggest difference with R2 in class A with EL-34s. It's a much more British sound. Going to simulclass brings a lot of bottom end from the 6L6s so that's very cool as well. Haven't tried 6V6s yet

Thanks for the input Rob. I'm even more curious now.....
