you may also need a voltage regulator and hot if the flyback blew too..
also ohm c36, it may be shorted and if so, you will need to replace it.
and to answer your question, yes the old school k7000 flyback is the same for most 13, 19, and 25" old school models...
now the 7400 and 7500 ar emore modern and nothing like thier classis counterparts.
