Yes, I hope to make it as original as possible in the future. ThanksI'm sure any good Marshall tech would give that a glance.

That's a lot to drop on any iconic amp. But if it sounds great after dialing it in, and its everything that you hoped it be. Excellent ! Nice to have someone go through it ,and assess,adjust and restore if neccessary? Even just to get its full true tone to shine.
Very cool piece !
