Welcome to the forum Androo, and to the world of Marshall. Great Amps. I hear the MA series benefit greatly from a tube change as well. Send us some clips and give us a review.

Greenbacks pretty much are the Standard. At least they would be my starting point on the speakers. You wouldn't go wrong with Tungsol 12AX7s in the Preamp with the exception of the cathode follower Tube, (usually V3 in a 4 tube preamp section or V2 in a 3 tube), as they have been known to fail from the higher voltage in this stage. Use an EH12AX7 here, and Winged "C" EL 34's.
Just a suggestion.

That's probably it, I'm leary of Evilbay:
Tung-Sol 12AX7 X2
Electro-Harmonix 12AX7-EH X1
Winged "C" (SED) EL34 X4 Matched Quad.
You don't have to rebias if you only change the pre amp tubes. If you change the Power tubes Yes.

Welcome to the Forum and welcome to Marshall!
Thanks! I've got the Tobacco Burst Slash Sig like you dude.
That's the custom shop model! Nice. Actually mine is the first - that one was in production as early as 2004. Mine saw the light of day Q1 '08.
Yours came out at the same time as the VOS in April 08. Correct? How do you like it plugged into your MA?
I love it but I definitely need a great cab for it. A modded SS combo is not the way to go!
Plus a change of tubes supposedly removes the subtle fuzziness of the boosted overdrive! Will get to that in the future.
I'm from Malta [Europe] so buying from online US stores is a major problem for me, which is why I went for eBay. The link I posted was from a power seller so I guess I could trust him/her.
By the way, you're of the opinion that I should change all 5 tubes?
Dump the SS. Get a 1960 cab. Unleash that beast!
Just checked... that cab is more expensive then my amp! I'm actually looking for a 2x12 not a 4x12.
Are Crate cabs any good? Behringher or Laney? Maybe a Blackstar HT212....
