Yikes...not again!
Hello Forum.........working on this nice little unit. It came to me with a blown left channel(one 2sd315 and a driver were OL). I replaced all driver tr's and diodes on both channels. DBT'ed...all ok. I then powered up on normal power....all ok.
I then wanted to set the bias....on the right channel it dialed in easy(20mA). On the left channel, I can't get it below 36mA........the vr9 is turned all the way down.
Should I check the emitter resistors for the left channel? What else could cause the bias to be a bit to high?....I checked the emitter resistors...they are ok.
Should I worry about the (almost twice as high) 36mA bias?
My voltages on the drivers and main outputs are fine.
