I would start by checking for bias voltage on the horz out tube.
also monitor the horz out cathode, if it starts to soar then shut down and firgure out why.
check the resistance readings on the fly.
I do like to install fuses for one thing it makes the horz out current check easy, not to mention I hope it would pop before any damage is done due to a tube failure.
example I use a 310ma on a hot that draws 220. I have seen the current soar when the horz osc was not installed (simulate a burned out tube).
I also like to install fuses on the B+ again just a bit over max (750ma on 500ma B+) the current tends to come up slowly, so you can be conservative on fuses (both B+ and cat)
