Perhaps  120VAC devices were more prevalent then or

either 120VAC or 240VAC  do not appear to share this issue.  Anyone know what 
the difference  is?

Modern amps that have 240v operation fed with (hot-hot-bond) setup use the  
centertap of the dual primary as the "nuetral point" NOT the home nuetral from  
the electrical system.  This eliminates the "lost nuetral" problem with the  
120v from the different phases senario.
