The 545 uses the [[154-098]] CRT.  With the limited CRT technology available at the time, the higher bandwidth of the 541 and 545 came with a tradeoff.   
The vertical scale is only 4 divisions, 2 above and 2 below the graticule center line.  The lower bandwidth 531/[[Type 533|533]]/535 retained the 6 vertical divisions, as used in most other Tektronix scopes.

Shorting the outputs of the vertical amplifier to ground can cause expensive damage by burning out the termination resistor network.

Starting at Type 545A serial number 29960, there is a 150 mA fuse, F1054, to prevent that failure.  This change was made available for instruments already built, in Modification Kit 040-227.
