try a rectifier diode lowest you got. get close as you can to 35 volts. check the resistance on the resistor network. i could tell you how to do voltage checks, if i do i would like for you to at least watch some u tube videos. need to see if you your 23v supply and 13.6 off the vert side of yoke and 7.6v supply from jungle ic. i am betting the output ic. get an idea on checking voltage and i can tell where to check.

you have a sa8.0a that's 13.6v. you could try it, but i suggest voltage checks first.

Looks like the sa7 is all I have besides a sa5

saw ur message. jbattles giving you good help so far. I will jump in with comments. 1) several resistors in around the vert IC look overheated. Cant tell for sure but they are the 2 light blue ones. 2) if you order parts buy a new vert out IC, they should be under $10. 3) look under the vert out IC. See if it has bad joints or is getting toasty brown. 4) try tapping the chassis & see if the pix returns to normal. The CTC203 was the last true RCA then they went China. I only saw a hand full & that means either not many were built or they were very reliable. Hence I have little knowledge of them. Good luck Zeno LFOD ! |

Note that most training manuals dont show everything. It would help
to get a copy of the service manual, any CTC203-## should work. Even just the vert area. At that point you can decide weather to troubleshoot or shotgun. 73 Zeno LFOD ! |

Should I just go ahead and order the ic?
