Dear people.
I try to fix my preamp the (Sphinx project 2) it had a bit current on the audio left audio output jack and my left speaker popd out when i turned up the volume. i found out that
adjusting the DC offset didnt had any affect on the problem. and i had to search deaper.
after a while of measuring and the switching technique i found out that when i changed the K389 fets from left to right and right to the left the problem appeared on the right output jack.
No i know that the trasistor is failing but there hard to find.
Let me know if you want to sell them.
I realy appreciate it.
My sincerely,
Theo Baas
