 Those old 'boatanchor' scopes make excellent AM modulation envelope monitors.

 I bolt a pair of SO-239's onto the back of the case right next to each other 
and connect their center pins with a short piece of wire. Then I couple the 
RF on that wire to one of the vertical deflection plates with a very small 
value of capacitor (but one with a high voltage rating), in the range of 1 to 10 
pfd., then I set the scope to auto sweep at a relatively slow (audio) rate and 
watch my modulation envelope. If you really want to get fancy, you can add a 
simple diode/cap envelope detector and feed that to the trigger circuit for 
autosync...
