Cap cans beginner question
#3

There should be 2 cans on this chassis. One is a single 25 MFD and the other is a 4 and 8 MFD capacitor.The 25 MFD cap has its negative tied to the center tap of the power transformer HV secondary while the negatives of the 4 and 8 MFD caps are tied to the chassis. Each can should be marked as to what value/values are inside.

You can use a 22 or 33 MFD to replace the 25 and a 4.7 and 10 to replace the 4 and 8 MFD respectively. All replacements should be rated at 450 volts. You can cut open the cans and install the replacements inside to preserve originality or just leave the cans alone, disconnect them and install the replacements underneath the chassis if theres room using a terminal strip. Hope this helps somewhat.
