These transistors can be made pretty well invincible by simply adding large
TO-3 heat sinks on them. I have been running a Tempest with this and the
LV2000 on it for almost 4 years 24/7 and I am running it FULL SCREEN (no
reduced height/width). BGMicro sells them for a few cents each. 3 of them
need to be "clipped" because 1 is entirely under the deflection board and 2
others are partially under it. The alternative to clipping is putting the
transistors on the OTHER side of the chassis so that the heat sinks are away
from the PCBs (which is an OK idea since they get better air flow and are
greatly insulated from the heat-generating boards).
