Gathering part information before I start on my Precision E-200-C. I have the later 1957-ish version. Like Bradley I was a little confused on the electrolytic cap polarity. They are C108a, b, c; shown on the schematic. After looking at this I believe that all three have the negative point connected to the center tap of the transformer. The positive of C108b and C108c is on each side of R111 and the positive of C108a is connected to chassis ground via the AVC+ jack. Am I correct?
Another Item I question is the line filter / choke. Should I replace the caps there as well? They are appear to be ceramic disc. There are 4 of them one appears to be a dual section (?) and 2 are hidden by the first line chokes.
