Does anyone know if there is a substitution for the RCA 198596 diode ?

( CR4402 on CTC-177 and similars )

Thanks

Thanks, but NTE does not have a sub, that's why I posted

I do not like the search on NTE site---their book was much better which ofcourse in NLA

Tried this, not sure how accurate this is. May want to call them;

That link takes me to Tiger Direct, the part shows up there like
many other places, but no sub, or a new part number
that also does not cross-over on NTE.

Some place some one mention a diode that according to him works
ok as a sub, I dont have the info here with me at this moment.

I am going to take a chance and try it, hope dont blow-up my
Horz Out Circuit & Regulator. The tv is fix, was dead, shorted
Horz Out & Bad STK Regulator.

Now is working but too much over scan, Vert overscan seens to come
down to normal after replacing a cap, ( 1.6 K ) but still too much
Horz Overscan and the Hourglass effect.

Thanks
