Ya, Man...

That test run up at your pad on your 8280 just re-ignited the dreams of a struggling, 28 year old musician who wanted one...

It is, thus far, the ONLY piece of gear from back then that actually sounds good to me today in 2021.....
 
So, the plan - at least at this point - is to add a grille to the top of the amp for improved cooling

When a Plexi is cranked up it sounds pretty good too.
But it's way too loud. It's louder than the band and PA combined.

But a SS 100W is about 1/3 as loud as Plexi...
which might be a good thing.
I would be thinking about 2 cabinets spaced widely apart, as opposed to - 2 speakers in the same cabinet. I think 2 separate spread speakers would enhance the stereo image a lot better.
Even if the 2 cabinets were each 1X12, I think it would work better.

But now you have the issue of a speaker that can stand 100 watts continuously, without weight of 60 Lbs. per speaker....

The Neo 250 provides clear, transparent tone and tight low end -- at about half the weight of a traditional speaker, making your amp cabinet easier to carry!

Marshall Valvestate 8200 issues

So my pops bought this head for me brand new back in the early 90’s when I was a kid and so it holds some sentimental value to me. Because of this, I am up for the challenge to try and fix it myself. When I first got it I used it for 3-4 years problem free then it suddenly stopped producing...

@syscokid pointed that out to me. Great resource should we encounter problems.

Have a brand new MG100HFX as a back-up....
 
Ive found the BRITISH MADE VS line (and really any of the stuff made in Britania) are amazing amps--
the china or vietnam SS ones are VERY good as well.... but fall slightly short of AMAZING --- lol
you should be able to get many many killer tones from it Robert

Congrats man
