ctc-5 ,but don't try this at home..:)
hey tim,nice score on the ct-100,gee,bummer about the tube have the usual white flaking..let me know if you need help on the chassis!!
since i am bored again and waiting the status of a 21axp22.. and have been working on this ctc-5 chassis.. soo.. i rolled over a 21fb22 on the garage floor and decided to check this ctc-5 chassis out,i am amazed i got color!!.. kinda dangerous how i got it hooked up.. but for testing i was so curious... after about 30 mins of running the fly starts to sizzle and wax comes out..not sure if it has corroded and shorted turns.. terry

You might try heating the slug with a soldering iron and see if it will move.

ctc-5
hey guys,I have been trying to iron out a problem with the H-osc going wild in the ctc-5 chassis..was perfect rock steady for awhile,then slowly started to drift and go way off freq..
and guess what i found? one of those mica caps..!! 82mmfd.. (or .000082uf). there are like 3 of various values.. so what would you replace them with? i am having a hard time finding these values.. terry

82pf 500 volt silver mica's are still available. I know AES has them.

21axp22 rebuild
ok here are some pics..of the bad tube next to the rebuilt tube..
i asked scotty if he liked rebuilding these..he said no!! and told me to tell anyone else if interested that the cost would be around 450.00-500.00.. i waited about a year.. i have installed the tube everything is great.. but no.. like eric H have no color..heh..i have a ton of controls to replace that are bad in the front of the chassis.. and blue is badly bowed down.. tells me something else is wrong in convergence area.. i could not get .39 mfd caps for convergence circuit so used .33 at a higher voltage rating..this chassis needs so much attention.. the first pic is of the tube in operation..with crosshatch,cant see the badly bowed vert lines in this pic thou..(left to right lines),i know it is a problem with the vert conv circuit..  .I am hoping that it is not a problem with the rebuild.anyone else care to comment on this problem?.. bigtime blue bow..looks like blue is frowning,and no controls correct it.. ..it seems i get problems after problems with this chassis,i hate to take the yoke and everything off and stuff it on the 21fb22 to see if i get the same results.. but i may do it..let me know any suggestions guys.. thanks terry Last edited by wiseguy; 09-11-2003 at 08:31 PM.

ctc-5
this set has no convergence board..no seleniums to be found on this chassis.. wish it was that easy..
this is the "lower end" chassis RCA had in 1956..ctc-5,and the thing is i am all excited to have found someone who would rebuild the metal 21axp22.and now have it in operation....works great,nice focus..but i am so confused about the blue bow.. terry..

Does this set use the plastic slider thingies for the convergence?
Wonder if flipping them over would make any difference  Another thought, probably a dumb one but... Could the metal shell be magnetized? I would think that would be more likely to cause purity problems but who knows. Last edited by Eric H; 09-11-2003 at 09:45 PM.
