i'm trying to find out if anyone has one with the output board(21 pins, standing up)showing the #'s on U1,U2,U3and U4. they should be identical on all of thes amplifiers..e-audio happens to have theirs buffed off, and i wonder if they are buffed off the other ones too. if they do have the #'s please pm me.
thank you!!

 

Rob... I'll check my EXT when I get home in a while and see if they have the parts listed there.

 

Sorry... all buffed off my EXT and my E-Audio also...

 

i checked all of my 3000d's and have U4 is a LM211, 3 more to go.
see if you can decipher any #'s..i used veg oil on q-tip to shine up the surface, makes it easier to see.

 

I got 2 200's here lemme check em for ya..might take a day or 2

 

thanks guy's i apreciate it.

 

Do you mind me asking why you are asking?

 

Well on my EXT they put what appears to be CA glue or something directly on the chip... so there's no real way of finding it out.. I'll see what's going on with the e-audio though..

 

yup mine are ground off... btw... did you burn your outputs too ? IRFP360 ? wow without those numbers for U1-U4 its gonna be impossible to fix as some of mine are actually melted

so I am also on the look out for these part numbers
