Hi guys,
I'm still rebuilding bakelite blocks and have a question. #72 on the schematic shows a .25 mfd single cap. it has 3 leads at 2,4,7 per the Philco service bulletin. The solder connections were pretty grimy/dirty, but it appeared there were only cap connections on numbers 2 and 4, however when I pulled it apart there were two condensers in there. One of them had very obvious leads to the top, but the other appears to not have been connected to anything. So I did some research and found out the part number, 6287-r, was changed to 6287-ODU and it shows a dual .15 Cap and different connections. On the number 7 terminal is a connecting point for resistors 67,68, and 26 also a feed to the 1 mfd elect. cap number 46.
If I configure this block with the double cap as the part number shows, that would add a cap between the filter choke number 71 and the resistors, which I would think would be incorrect. Can someone please verify this so I can continue on, this was pretty butchered in the distant past and my mind is fried at this point.
Thanks,
Glenn
