...ok. so the cap in question is inside the network, even tho its showm next to the ringer in the schematic? i see a 50 ohm resister above the cap in the schematic also, and these compontents are in the network, correct? its been a long time since i read a schematic, so pls bare with me. so if i put a 300-400v 0.1uf cap across terminals a and k, will this surfice? oh, btw, the network shown in the schematic has the number 4258, the one in my phone is 4228, does this make a diff? bob
