Hi guys i have a Music instrument keyboard Technics Kn2000,that i few years ago have shorten the audio line out on the Left Chan,because of shorted cables.
last year i decided to repair it and i did repared it by changing Trans. A1015 and the left Chan on line out was working again,but since then when i switch on the power, it powers up but some times with no sound,i have to push power switch off and on button one more time or two times and some time 3.Besides that it works great,
I posted sime pics of the circuit where i swaped the tran,A1015 should i look at anything else besises the transistor it self, that might not be the right specs i found this one on my electronic components scrap. thanks in advance.

no audio out of the instrument channel, but some weirdness is gone and sounds now clean on the second channel. So I put my laptop on there and cranked the music full tilt. Sure enough, it goes crackle and pop with the bass in rhythm. Put my signal geni on it and sure...
