Re:Scopes

Hi,

In my opinion the 465 was the best general purpose scope Tektronix
ever made. It had excellent writing speed and focus. Its weakness was
the voltage attenuators. These were easily prone to mechanical
malfunction and rendered an otherwise working scope into junk because
of the expense in replacing them.
