    I might actually get mine finished this week - I have a bit of time during the day for a change.

    So I got all of the capacitors replaced on the tone board tonight, except for two. I don't really understand the orientation of a couple of the Wima caps. I'll look at it again in the morning and take some pictures. Getting closer to the end!!

    I just completed my tone board and was confused about the WIMA caps as well. They are non polarized so they can be put in either way. I got this information through Randy who has been extremely helpful through my process. I also read up on them. There is a negative sign on them so I used that to follow the original path from the former ELNA electrolytic caps, just to be safe. I should be ready for a "current limiter" power up in a week. Good luck with yours.

    I knew they were nonpolarized - it's how he doubled up on a couple of holes to make them fit that I need to study a bit more.

    Here's a picture of how the 2230 C411 and C415 caps were installed at the factory. The 3.3uF/50v and 1uF/63v WIMA film caps fit in the same holes. A bend in the 3.3uF/50v cap makes it so they both fit and go all the way through to the other side.

    Just finished the tone board, going for the P700 phono amplifier.

    C713 had a substantial amount of rock holding it to the PCB. Should I secure the replacement cap in similar fashion?

    Care to help identify the base, collector and emitter?

    The KSC1845FTA transistors are installed on the phono board just like the silkscreen on the board shows.

    I assume these LEDs are polarity insensitive?

    Maybe they are polarized - there is a heavy leg and a light leg. I oriented both of the heavy legs inward. I also oriented the printing on the LED base the same as the original lamp. I'll wait to solder until I receive guidance.
