I notice 2 thin yellow wires in the front left are disconnected, anyone know where they should be connected to?

The FET I tested with, and the eventual Digi-key replacement I installed both worked fine. I ran through the alignment procedure with the Digi-key part installed. So far as I can tell, the radio is fine. <br /><br />I'm not a transistor guru, but I think in this instance a PNP or a FET in that position would have worked equally well. It appears to just be a switching transistor. I don't THINK much current draw was expected through that part, but if it WAS a PNP, perhaps a beefy FET might be more to the point anyway. Something caused the other one to pop! - Mikekd2eathttps://www.blogger.com/profile/00709005938404511244noreply@blogger.comtag:blogger.com,1999:blog-1904678747905486184.post-84116329058872671692017-03-11T19:20:30.830-08:002017-03-11T19:20:30.830-08:00should not have worked , service manual shows fet ...should not have worked , service manual shows fet q4 on drive, pnp on control 2sb1132 or 2sa1736jamesrnzhttps://www.blogger.com/profile/01261471628753249562noreply@blogger.com
