    I have a EuroTube matched set of JJ's that I got for my Blues Jr. I have since got rid of the BJ and now have a Marshal Class 5. When I sold the BJ, I pulled my nice JJ's.

    Should I put em' in my Class 5?

    What will they change (e.g.headroom, tone, eq)?

    Thanks!

    You just have them sitting around?!?! You want us to tell you what they will sound like? Why don't you just put them in there and find out.

    Isn't the Class 5 a single ended amp? If so it should run off one 6v6. With that said, I think JJs are my favorite 6v6s out there. I like them just as much as my NOS 6v6s. YMMV

    Yep, JJ's all boxed up sitting in the closet!

    2 x el84, 1 x 12ax7.

    I am too lazy right now, to pull the tubes, since the C5 is new - with new tubes :)

    I just wanted to get people's thoughts before I pull out brand new tubes.

    My mistake....I thought the class 5 ran on a single 6v6. Either way I love JJ tubes. I've used their El84 in a Valve Jr and my Ac15. They are pretty much my go to tubes.

    So what do JJ's bring to the table versus the Marshal branded stock Chinese Tubeys? Thanks again!

    I don't know if they are "better" but they are better built. I replaced the tubes in my Vox about 3 months ago and it was like buying a brand new amp. I think one of the tubes was dying though because it about doubled the volume of my amp. That was going from Rubys to JJs. Ruby tubes are good though too.

    What's it going to do to your amp sonically? Im not sure you'll be able to tell much of a difference while clean but you might notice a difference when the amp is cranked.

    I don't have any dying tubes, I just didn't want to waste a good matched pair...

    I changed stock tubes (probably some Chinese) to JJ's and there is a bit difference in overdrive.

    Your are correct. I had a minor moment of dyslexia! All I knew was I had all the tubeys covered from the blues jr purchase.

    So thats pretty much it, different gain characteristics?

    What do you want them to do? What I mean is, is there something you dont like about the Class 5 right now?

    Nope, just checking my options before I change anything. Thanks all for your replies though!

    I bought some JJ's to put in my Class 5. My amp sounds great to me stock so I decided to wait until the stock one's crap out on me.

    JJ's always sound brittle to me...brrangggg. I prefer the New Sensor Tungsol or Mullard.

    Put JJs in my brother's C5 and it sounds great--better than the stockers...I'd pull em and replace em for sure. JJs sound better in that Marshall than they did in my Blues Jr I had.

    You actually don't have to pull the chassis on the C5, you solely have to take off the 3 piece back; which would almost be as time consuming :) But thank you for your support J5!!!!

    Conversly, I actually have the C5Head . . . but I just wanted to get other people's opinions as you said!
