Hello,
I have a working Aleph 4, however when I look with a scoop on the traces of the + and - voltages of left and right channel I get very strange views... Only the first trace looks like I would expect. both channels are wired the same. They are all very different. Timebase and amplify are all the same for all pictures!
I have 0.22uf 250V around the rectifier bridge and across the + 0 - side of the elco's. You can see this on a picture below.
