One side of that Candohm is at -20 volts to ground, the other
at -10 volts to ground. The only fuse it could blow is the one in the
B+ line to the horizontal output transformer, by reducing (to -10 volts)
the fixed grid bias on the horizontal output tube ... which will even then
get bias from the drive waveform. If it were to open, it would just
just ruin the vertical centering and slightly raise (to a higher negative
voltage) that fixed grid bias.
