Jimmy Page's KT88 Marshall 1973

[Sulleeenfield]

Hello, new guy here.

I want to recreate Jimmy Page's 1969' 10xxxx JMP Superlead fitted with KT88s.
Is it as simple as making 69' build, trowing in the KT88s and re biasing? What kind of mods (if any) has to be done to a stock 69' plexi to be able to take KT88s?

Also where can I find period correct parts?

This would be my second amp build.

Cheers
