R4A: It appears that one or more sections of the Sangamo power supply filter cap are defective, since I measure 5.2 volts p - p with a scope at the junction of diodes D4 and D5 (156 VDC). And my power transformer gets very hot.
The cap is in a single aluminum Sangamo chassis mount with: 100 MFD 200 VDC 100 MFD 200 VDC 100 MFD 200 VDC 20 MFD 20 VDC 1) Anyone have a spare from an R4A they are parting out? 2) Suggestions for a source for this filter cap from others who have gone before me. 3) Have improvisors found discrete caps from a source (pse recommend one), left the chassis mount unit alone, and mounted these discrete caps under the chassis? 4) Has anyone actually drilled out this filter cap shell, and mounted discrete components inside? Any other ideas or comments appreciated.
