Re: Replace chips in SEM filter

2016-09-17 by kevinfglover@yahoo.com

I don't have one of these or can seem to find a schematic. However, a magnified view of a image of the A106 SEM seems to show the 14 pin chip being a TL084CN. A very common,inexpensive, Quad Op-Amp. With the ICs being socketed, (danke Dieter) there should be no problem replacing the problem part.
A quick look on E-Bay , the first one on the list 5 for $3.00. But, beware . A lot of these cheap parts out of the orient are recycled, untested parts. My advice, pay a few extra bucks and get new ones from a reputable dealer.
