Mrjukebox160, you are correct. It is indeed a 1000 pf cap. Although the one listed is not the one shown in the picture ! Obviously an error on Sams part. The schematic does not match the photo part number. Sorry, I was scratching my head.
I had another question regarding the networks. I've watched a lot of Bob's videos on the Predicta's. Is K2, the only network (vertical section) you have to use 1000 volt caps on ? I know the one cap on the chassis board C14 .0015 mfd is the only one rated at 1000 volts, and the cap on the network (1500 pf) is directly connected to this cap. Will a 2200 pf @630 Volt poly on K2 go "poof !" ? Can you get away with 630 volt caps for the other networks ? I ordered 1000 volt mica caps from JustRadios, but his micas stop at 1000 pf. You then half to use the poly series. I ordered 3 -1300 pf @ 630 Volt 1% for using with the 2 - 47K resistors on the K3 network (also vertical section). I know his "regular" micas are only rated for 500 volts.
