Fuzzboat, stop name/schem dropping and just drop it bro! I've heard you mention it before and this is the DIY section so giv'er! BTW, the friedman "correct spec" brahma is about 2 or 3 components different than the standard brahma. Brings out the highs a wee bit more to my ear but the best MTS module I have for authentic Marshall JMP/800 tones. Someone send me the schematic or layout for the brahma and i'll just pencil in the diff values. The reason I figure i can is because A. This was supposed to be the correct spec shipped from the factory anyway, B. Friedman is busy enough with his new amp builds and modding real amps, I doubt these are a priority. GTO is supposed to be close to the BE also.
I also found a lot of these layouts to be similar + or - a few values... Between the scary and SL+ there were maybe 3 part differences. SL+ and brahma, same thing plus the extra stage wired in for more gain.. there are similarities among the real amps as well but these were very very close. I keep wanting to try a plexi but i realize it will essentially be a brahma with slightly diff voicing.
Great work on this schematic JudMan! Love to see this quality work in the DIY section. Very true, isn't there only 3 different circuits? Considering every new amp is typically based on a previous design, modded in some way, it makes sense. Slightly off-topic.. Everyone's got their tones, but it would be interesting to come up with at least one MTS community mod.
