Fujifronier , I dont have the exact schematic book for your set , but I got one that might work , what I need to know is what tubes your set has on the tube list then I will compare this with the ones that I have some of the RCA's had the same parts but when next years model came out they put the parts in a different chassis the one's that I have that are similar are for the

KCS 108 chassis
model 21 vf 8695 from 1957

Does anyone Know if this will help fujifrontier ,
or are they different ? it's too bad the tv wasn't a 1951-54 models because I have a stack of them , perhaps for every rca tv made in those years .

You can possibly get the set going without the schematics , the one page that you have will do it , the recap. is not bad to do , the wax papers are easy . I have done it with no schematics and the easiest way is to nip off on lead at a time on the cap and solder the new one in . A friend of mine that has been doing radios for maybe 40 years told me this one , Cut the wire off the old cap and make a little hook with a pair of needle nose pliers and trim the new cap and do the same and then you can hook the two looks together and pinch them with the needle nose pliers and solder them together . then do the same on the other side . I've used this method over and over for years and had exellent results .

Make notes of everything you take apart and , What I do is take the camcorder and film anything I might question in the future when I assemble it . Also if there is no tube list take a pencil and write the tube numbers beside the sockets . once you pull the chassis it will look alot more simple , just do a couple a day , thats the easy way . I would say there were 30 in the set . best of luck on it .
