IMHO, one of the (to me) big problems with a wobbulator (my RSGB 
Handbook from many years ago has one in it) is that in those cases in which 
the wobbulator has a horizontal scope sync output, that output is a triangle 
wave.

It should be a very fast rise-time sawtooth instead.

Otherwise, the scope trace shows a double-hump which makes it 
considerably less easy to interpret.
