-The 547 is a 50MHz scope that takes letter-series and 1-series plug-ins.  It has two identical timebases which can control two traces much like the familiar dual-trace vertical.  (This "Sweep Switching" feature differentiates the 547 from the 546.)  Triggering is done with tunnel diodes, which tend to shift in characteristics as the instrument ages.

 A replacement CRT for the 547 can be taken from a 543B, 544, 545B.546. or another 547.  A common problem
