anyone have the hk 690 service manual with bias adjustment set and test?
The HK690i service manual is already here on hifiengine; look under stereo receivers. The DC balance and idle current adjust are on page 4.
hi, i need the service manual with bias set for the hk 690 integrated amplifier, not for the hk 690i that is a stereo receiver.anyone can help me?
I would try the HK680 procedure if the amplifier appears to be close enough.
