Rebonjour Wilfred
Bravo for the new 465.
Since the 1970s the successors were improved, so 465B has better control, LED not incandescent etc.
Nowadays the last of the analog CRT scopes from Tektronix are great buys, 2465,2465B, 2475B, etc.
A 1990s scope has much better reliability than the 1970s you have.
Just my experience
