I've run into an issue.
Recapped the PS (just the caps, no diodes or transistors yet), fired it upon the DBT (no light emitted from bulb), set Offset and Bias, got a relay click. Everything was fine.
Moved onto the Driver board. Replaced all caps, the four 2sa726's and the variable resistors. Fired it up on the DBT and the bulb stayed about half lit and I get no relay click. When I tried adjusting Offset or bias for both channels my multimeter readings do not change. There's also a small vibration on the board you can feel if you lightly touch it.
Doing the bias adjustments on this unit you take out a fuse and hook your leads to the fuse clips. When I took the F-02 fuse out for the right channel and turned the unit back on the bulb did not glow and the vibration was gone. The bulb glows and the board vibrates when doing the same for the left channel. Which would lead me to believe there's something wrong in the right channel of the board, but I still can't adjust anything with the VR's on the left side (which leaves the bulb dim and there's no vibration) either.
Where do I go from here?
