Hi all!
Why we can get mashall's cuicuit diagrams?i think the diagrams are the secrets of the company.
If we all have mashall's diagram and we all can build AMPs like marshall.Who will buy marshall?
:loco
A complete product is much, much more than a circuit diagram.
teemuk is certainly correct.
Not only that, but Marshall schematics are readily available.

what's the different between schematics and circuit diagram?
None that I know of.
Circuit designs are actually not protected by copyright, unless you design something that is considered new technology and you patent it. Most of the circuitry in Marshalls is based on designs and technology that date back to before 1950, so it can not be patented because it's pretty much considered "common knowledge" for electrical engineers.
A circuit is just like a recipe for baking a cake. But have you ever had the same kind of cake, baked by two different individuals? they taste different because everyone uses their own methods of making it, even if the recipe is the same.
Also, building an amplifier is not something everyone can do, it takes time and skill, and sometimes a company like Marshall can just do a better job for less money than you ever could. (getting back to the cake analogy, why do we have bakeries if we can all bake our own cakes?? Well, because they make some fine cake, and maybe we just want a damn cake without the hassle of making it :))

Thank you very much! :)
different engineers ,different workmanship.
You can copyright your schematic though. Redraw it and you are OK.

Where can somebody go to get a SS Marshall schematic?
Thanks for the help.

Thanks for the tip. SH and Dr Tube were the first sites I tried, and then many others. They do list some of the SS Marshall's, but not the ValveState 2000 AVT50. Thanks for your efforts.
