I bought my 2012 Mark V used, so I don't actually know how much it was used?? To be safe, I bought some new tubes a few weeks ago - some JJ 6L6gc tubes and put them in my amp..... They smoothed out the top end, brought out the mids and lowered the bass just a little and tightened up everything. Over all, I liked what I heard much better than the Mesa tubes. Then I started hearing about how the Mark V is biased much hotter than other amps and requires lower output power tubes to compensate for this. I also read several horror stories about resistors blowing and stuff getting fried inside of Mark V's due to "too hot" of power tubes.
So last night I put the Mesa tubes back in so I didn't cause any damage to my amp, but I really miss the JJ's. I'm not worried about the warranty since the guy I got it from never gave me any paperwork (and I have no way of contacting him) and I've already changed speakers in it. So I'm just curious if Those JJ's are going to be safe to use, or should I just stick to Mesa tubes (even though I like the JJ's better)?
