    Unit runs but no speaker output kenwood KR-6030

    I have finished my work. The new lights come on except the one for stereo, I reversed the bulbs to no affect, anyway, the unit powers on, relay clicks. I have no DC voltage in speaker outputs, I also do not have any AC in the speaker outputs. There is some faint crackling in the speaker. This unit cranks up loud so I had the volume on very low. Everything seems to be fine but I can't really check the switch until I can get sound out of the outputs. I was going to do caps for the power supplys and the tone board but thought if it was cranking loud at one time maybe just leave it alone until it really needs them. So, I'm at a loss for what to check and do I check with the unit on or off. I assume the problem may be in the board with the relay because all the caps are in the same positions like left and right. Could anyone give me a few ideas on where to check. I really appreciate it. Oh, the tuner does work and the meters work also. Not sure I care for the blue lights in the meters but it may grow on me. I just want it to make sound. Thanks I have a chematic on this unti.

    Well, I found a loose wire or rather a broken wire and fixed it however now I find I only have music coming out of the B channel. I think the problem is in the switch (on/off, A, B, A+B). I think since you can't get a new one and I am not experienced enough to install new wafers even if I could find the right ones I'll just leave it alone and listen to 2 speakers on the B channel. Maybe I'll take it to Tampa someday there is a large HiFi repair place there. For those who have helped me R_J, Agent24, and I think tdj thanks a bunch you guys are great.

        There are 12 pins on the switch plus the on/off. How could I bypass it?

            If you look on my other thread page 4 you will see R_J helped me out with that. The wires are where they belong I just don't think the switch is connecting correctly to the wafer. I think the wafer is the problem, however, when I shake the switch it turn the unit off and back on again if I shake it a second time. Wierd. I have speakers on channel B only, left and right just not for A or A+B.
