Hi I trying to determine the electrolytic cap's C8 & C9 which is neg. and positive. the existing electrolytic cap is not labeled. It has three wires coming from it, one is black going to the resistor R5 & R6 between them. The other two wires are the same color. What is confusing to me is how C8 & C9 are connected. Is the neg. side of C9 connected to pos. of C8.

This one is indeed a bit different than what you usually see. This pair of caps has a common positive, and separate negative leads. The single wire which goes to the rectifier filament is the common positive for the two. The other end of each is the negative terminal, one going to the R5-R6 junction and the other to the transformer HV winding centertap.

Greg, the capacitor was not labeled either, so thanks for your help. This is a new one for me.

Thank you Tom, I could not go by the cap because there were no designation on the cap itself.
