Well, you can but try! If it gets too hot it is useless.
Don't forget the vital formula relating minimum number of Turns N, Core
cross sectional area A (m^2) RMS Voltage V, and Saturation flux density
B (use 0.15 to 0.2 Tesla for most ferrites) :
V = 4.44.F.N.A.B
You would probably do better using surplus SMPSU components than old TV
cores.

What about EHT transformer cores salvaged from old TV sets ?
Any experiences with them ?
