Made mention of this elsewhere so..
Tektronix equipment from the 1960's to the 1970's are just fantastic for our hobby, hands down. Used HP ones from that era are perfect as well. Also....Most all are cheap now if your wise. When I was in school I could not afford a scope of any kind!! Take advantage of this now.
(Copied this from of few of my fav sites about scopes)
453 (50Mhz bandwith) is more than enough for audiophiles
454 (150Mhz bandwidth) is sufficient to work on most hobby oriented digital logic
453 and 454 are sturdy, rock solid, and reliable.
465a/b - 100MHz, dual trace
466 - 100MHz, analog storage, dual trace
468 - 100MHz, digital storage, dual trace, RS-232 output
475 - 200MHz, dual trace, 2mV/div sensitivity
485 - 350MHz, dual trace, fast!!!
I have a TEK 475. In 1973 this cost over 2 thousand bucks...... I got it for less than $100! a few years ago. It was a bit jumpy on the screen when I bought from a guy on eb**, but found a few bad caps in the power supply! BANG. Easy fix as we know, Got a real nice scope now.
I also got a few more tek scopes as well, but every day, I just pull the switch on my 475, I can see anything in radio or TV.
