Shorting the outputs of the vertical amplifier to ground can cause major damage.
Shorting the outputs of the vertical amplifier to ground can cause major damage by burning out the delay line.
In the 545A, there is a 150 mA fuse, F1054, preventing such damage.
In the 545A starting at serial number 29960, there is a 150 mA fuse, F1054, preventing that failure.
