In a dark room, jump the cathode fuse and watch the output tube as the TV warms up. If you see the plate begin to turn red, shut it down. If there's no red and the TV lights up with full raster and no nonlinearities or compression in the raster, it's probably good, but there might also exist an intermittent loss of horiz drive that will stress the output tube and open the cathode fuse, which is why you don't want to leave it jumped without constantly watching it.

I'll get the clips today so I know it's jumped and I'll watch it.
