I just looked at the documentation of the 38-116. There are actually 3 electrolytic condensers used in the power supply. Two, part 141 and part 142 are simple 8 MFD electrolytic condensers. Part 140 is more complex, a 2 section electrolytic with both sections in one can, with common negative. BE CAREFUL when wiring these condensers. The negatives of all three DO NOT GO TO CHASSIS GROUND ! If you make your reproductions as I show in the link I gave you this won't be a problem since you will have both the positive and negative leads coming out of the bottom, and can easily connect them as required. All three negative leads connect together (eventually, not necessarily directly) and to the green and yellow wire from the power transformer, the HV secondary center tap, and to one side of part 128, the 490 K resistor, one side of part 134, the 3 K resistor, and the blue and white wire to the speaker field coil. Looking at the circuit, I see no reason why you cannot use 10 MFD axial 450 V or better 500 V condensers for all 4, parts 141 and 142, and both sections of part 140. Also, since both sections of 140 will be 10 MFD, you can wire either positive lead to either place and be OK. Again, hope this helps you. Feel free to ask questions. If I can't answer, I'm sure someone else here will be able to.
