hello from Corsica

Welcome nico56, welcome. Really good choice in building a JTM50. Any variant (there were a few) of this model will be a great amp. Here's a gutshot of an original (from the Marstran Historical Data site) that may be of interest regarding layout.16267470759023629241628206400749.png Note it has been recapped, including bias supply caps & the bias supply modified with the addition of a vertical trimpot, also has screen grid resistors fitted.
I would say member @67plexi is our resident vintage Marshall expert. IIRC he owns, among other very desirable amps, a really nice JTM100. Cheers
