I need help finding and identifying transistors

I am trying to repair a GE AB 40 meter. I can't find the transistors any where or a schematic of the meter. transistor numbers fs33128 and k91.
I located the 2n4249 and it crosses to a nte159.
Calibration will be a problem but there is only 4 pots.



Re: I need help finding and identifying transistors

The K91 sounds like a FET (2SK91?), but it does not cross to anything. The fs33128 might be made by Fairchild Semiconductor; I believe they are still in business. You may be able to experiment with generic transistors to get your meter working again.

Re: I need help finding and identifying transistors

all the labels on the printed circuit board are E.B.C.
I also saw places on the net where they were labeling the k91 as a FET.
