hello vargasmongo3435.
have much reason.
I bring in foroselectronica YIROSHI excellent amplifiers.
Too bad he was expelled, but just the few amplifiers that provide very good achievement.
I must say that many are not but if your designs are good Redesigns worth admiring.

Hi forum friends, I have the layout of the amplifier jbl Megatech Urei 6290, but only I have the layout, one of you will have more information on this amp, or someone can tell me if this driver works well, I Realize the simulation of the same from layout, in multisim 12 and apparently works fine, but I would like to get the schematic of it.
thanks for your comments.

Regards.

Default jbl Megatech Urei 6290

Quick work p.c.b. jbl Megatech Urei 6290, I think P.c.b. can easily be designed if one have layout.
