Fairchild S42728 replacement needed

Don Nebel · 17th July 2007, 02:54 PM

Hello, I am trying to bring an old amplifier back to life. The amp uses the Fairchild part S42728. This is a small signal transistor TO-39 case. I can not find any info for this transistor. I tried Fairchild, they were no help. The amp was made in the late 1970's. Thanks, Don

Tell us whether it is the Vas or a driver, the B+, and we can tell you what to use.
