Maybe also the mod in a plexi made by Friedman

JOSE ARRENDONDOS was the guy that did the original mod that Freidman uses.  These mods vary from amp to amp according to the circuit.  Check out the SIR mods Mike_J is currently discussing.  They are the same.

Lots of information at Metro Amp as well.

Thanks Ed, I have tryed a BE100, its sounds very good and I would try to build it
but it seem difficult to find schematic

You probably will not find a schematic.  Same as a Dumble.  These guys, Freidman, Cameron feel their builds are secret.  There are some common things.  Once the circuit variation is known any builder can mod amps the same way.  If you start with a 100 watt marshall and add 2 gain stages then simply tweak the amp for a tone you prefer.  Experience is handy here, but not necessary.

If you look at the majority of the old modded Marshall usually you will find they have added a tube prior to V1a.  This tube becomes V1a and V1b.  The next tube then becomes 2 gain stages.

Check the attachment, it will get you close.

thanks a lot Ed, I imagined it was nothing strange, I
think I can try starting from a standard plexi schematic


thanks again

But this is the same mod that Friedman does?

Or it could vary accordingly to the different type of schematic
