    I am always playing with tube swaps and speakers. with the G12H anniversary ( not my favorite speakers ) but not bad i was not getting a low end i wanted. but once i find the right speaker combination who knows might go back to standard EL34's. its never ending with me

    My blue special edition head has shipped finally, should be here in the next week.
    Without rereading the million pages here, I see the post abpve about KT77s. Does anyone know if KT88s will physically fit in the head? I may want to play around.
    Cheers

    Hey Jethro I remember your last post when you got the cab...that blue color is really nice! Maybe you can post a new pic with your head + cab when you get it.

    BTW - where did you get the special edition? I don't remember seeing it advertised anywhere.

    Welcome to the forum
    Sounds as if you are getting your new amp dialed in to your liking.
    Cheers

    I've seen KT88's working which meant the Fucking bias resistor is covering some ground. Fuck KT 77's they are an ear that found a cleaner pussy. I love the way she moans. Most boys might. 6550's? Marshall. Light it up! The right tube penetration really can.

    The bigger tubes will fit sans headshell. Not worth it . The 20 watt will do so much. It's the Fucking price for small iron/glass.

    Reamp for more. Look where it is. It ain't tubes with the iron included.

    Sounded like 77s or 88s gave it more low end thump. All I was checking. Didn't know if they would fit stock. Sounds like not.
    Cheers

    Cool man, I know it’s been a long time. Looking forward to reading your thoughts on it, especially with you being a gigging musician.

    Assuming you get it next week, :fingersx: how long of a wait will it have been?

    KT66's will barely fit, but you have to slide the chassis out to install/remove them. Don't know about other tubes.

    Have you tried Kt66s’ in your SC20? If so, what are your thoughts?

    No, I have not. Someone in a previous post had asked, so I had done a test fit. I haven't seen too much info published by Marshall, regarding what tubes "should" work fine in the Studio amps. The design allows for use of alternate tubes, but the amps were designed around EL34's, and I'm guessing somewhat optimized for EL34's.

    It's cool hearing about other brave souls' tube swapping adventures here. Myself, not exactly being a vacuum tube circuit expert, I'm too afraid of 'blowing something up' if I stray too far so I just stick as close to stock tubes as possible. Luckily I'm really liking what the EL34's are giving me! Good to know that there are alternatives though, given the fact that there are only a handful of tube factories around the world.

    Absolutley can put in almost anything as per @santiall. I hear that KT77s give it more low end thump in the combo but dunno if they fit the head version. Sounds iffy unless they are the same height as 66s.

    Do you happen to have a link to that post? I know there's been discussions around it, and I know it's "doable", but I still find it odd that Marshall doesn't mention it in the user manual, at least I don't recall seeing it.
