Hi,
I have one of these sets and am in the process of recapping it. One question is the orientation of the two 4MFD electrolytics in the large can, since it's not shown on the schematic. Are both negatives grounded to the chassis, or should one positive lead (and if so, which one) be grounded?
Thanks,
Rick
