well since the ctc15 flyback im sure is in demand but is no longer available so i think it time for all of us tv people to put our heads together to come up with a way to use a different or maybe modern flyback to continue using these old sets that we all work hard on to restore, but what happens if the fly goes bad, then what, just use the set to put pictures on. what i think we need to do is to look into voltages and pinouts and just maybe someone can come up with a safe and reliable way to substitue a modern flyback for these old sets that refuse to die thanks to us. anything is possible and if humans made or engineered it than humans can find the solution to something we already made, where there is a will there is a way.
