Hello Fellas , I've started going through my old Japanese Alpine car audio stuff looking for projects and found My 3011 EQ stopped working . After an inspection I found the fault to be transistor 2SA913 . When I removed it ,it would test fine so I figured bad solder joint and put it back in , again not working ?? but found when you push on the transistor it would work so I pulled it again and this time it tested bad , crazy thing is if you squeeze the transistor it test's fine LOL . live and learn guess . Anyway the problem is I can not find a suitable replacement for the 2SA913 . closest in the T0 220 is 2SA 1859 but it's only 1/2 the speed . I found something in the TO 126 package but it's a little lower on wattage the pin out is reversed but that's easy just flip the transistor , could I just add a heat sink to hep it deal with the little extra wattage . Maybe someone with more experience then me can look at the specs of these transistors and let me know what they think . Or have suggestion for other viable replacements . all advise welcome .. cheers Roger
